License plate check digit

Also,
SBS (6500+X) = SBS (X)
Example being SBS 3616E and SBS 9816E. -
TIB 9xx ? = SBS 96xx ?
for example..
TIB 928 G, SBS 9628 G
TIB 933 R, SBS 9633 R -
It's just addition of 8700 digits. There seems to be some sort of pattern for SBST regoes. Working to crack it.Originally posted by off_service:TIB 9xx ? = SBS 96xx ?

Exactly same pattern applies for every series not just SBS series. Be it EA - EZ, SH - SHB, PA - PB, CB, GA - GV, TIB, FA - FZ, SBA - SBZ, SCA - SCZ, SDA - SDZ, SFA - SFZ etc etc the pattern of emergence is exactly the same. They just look different because the starting check digit is different.Originally posted by SBS9818A:It's just addition of 8700 digits. There seems to be some sort of pattern for SBST regoes.

I've long cracked the so called "pattern" :p -
Yes, I know. But will have to work the SBST one out first before using it for the rest.Originally posted by AntiDennisLance:Exactly same pattern applies for every series not just SBS series.

Look properly. It's TIB 9xx and SBS 96xx and not both SBS.Originally posted by SBS9818A:It's just addition of 8700 digits. There seems to be some sort of pattern for SBST regoes. Working to crack it. -

It was opened by Teo Chee Hean on 23 August 1996. The first batch of AC Double-Decks were Leyland Olympian from SBS 9000 S - SBS 9199. I reckoned that they were introduced in phrases.Originally posted by pkchukiss:It is Singapore's first Volvo Olympian superbus, opened by Teo Chean Hean in 1994 (forgot what date).
Now I was absolutely positive on the check digit being A. Nevermind, I will try to keep a look out for that bus and confirm. -
You are right. From 9000S to 9199C, it took almost one year for the buses to be introduced. 9199C came out just around the time as 9200G.Originally posted by service_238:It was opened by Teo Chee Hean on 23 August 1996.

i suppose they signed for 200 LO3x's but were apprehensive bout those LO3x's after shipment and they slowly took them in while hoping to discuss with Leyland to review the contract to stop buying them in but apparently failed.. so they came in slowly.. meanwhile the discussions with Volvo were oncoming probably cos SBST needs the DDs to cope with demands and they could have spoilt their relationship with Leyland by trying to go back on its words..
and tat's my deduction only.. -
Not really. As the buses are bodied by SBST themselves, generally they will take longer time to come out. Just like the Super Olympians, Habit buses and the gassies, they are kept for a period of time before going into service.Originally posted by ^tamago^:i suppose they signed for 200 LO3x's but were apprehensive bout those LO3x's after shipment and they slowly took them in while hoping to discuss with Leyland to review the contract to stop buying them in but apparently failed.. so they came in slowly.. meanwhile the discussions with Volvo were oncoming probably cos SBST needs the DDs to cope with demands and they could have spoilt their relationship with Leyland by trying to go back on its words..

Can't be because Volvo had already absorbed Leyland at that time. If SBS was comprehensive with the LO 3x, then why would they order over 400 VO 3x? The VO is an LO with Volvo parts, after all.Originally posted by ^tamago^:i suppose they signed for 200 LO3x's but were apprehensive bout those LO3x's after shipment and they slowly took them in while hoping to discuss with Leyland to review the contract to stop buying them in but apparently failed.. so they came in slowly.. meanwhile the discussions with Volvo were oncoming probably cos SBST needs the DDs to cope with demands and they could have spoilt their relationship with Leyland by trying to go back on its words..

is it? i didn't know that.. but the Volvo engine seem so much better than Leyland's.. and i know the body is assembled in Hougang, Singapore..

Yes, the VO is a LO outfitted with Volvo engine and electrical components. Some VOs in HK have Cummins LT10 engine! Besides, when SBST bought in the LOs, Leyland was already owned by Volvo and about to be shut down permanently.Originally posted by The_Bus_Guide:Can't be because Volvo had already absorbed Leyland at that time.

Indeed. And that's more than enough reasons why we should be proud to have the last Leylands ever in this world.Originally posted by SBS9818A:Yes, the VO is a LO outfitted with Volvo engine and electrical components.

Cheers and warm regards -
Yes, that's very true. Even the B10TL, darling of so many forumnites, is a direct descendant of the LO, with some modifications to the chassis. Just think, if Volvo hadn't bought over Leyland, we'd be riding on B10MDs and B7TLs.Originally posted by Superbus:Indeed.

I realised that 2 Car Series has the same check digits with SBS
They are SCL and SDE. Check them out. You'll be surprised that those car check digits are the same as SBS.
I'm not sure of TIBS. -
For trucks GU also has the same check digits. I also noticed the same for SDE. Out of interest, RU registrations follow SBST check digits.Originally posted by service_238:I realised that 2 Car Series has the same check digits with SBS

SH-series registrations share the same check digits as TIBS registrations.Originally posted by service_238:In addition to that. YJ also have the same check digits. -
i've done a mIRC script that will return the suffix of SBS and TIB licence plate numbers.. download the file by right-clicking then "Save Target As" and then selecting ur mirc directory (usually c:\mirc), load the script with the command "/load -rs liccheck.txt" on any mIRC window and press F11 to start.. u can also view the contents of the script alogrithm with Notepad or any text editor.. will be trying to do a JavaScript version so Pocket PC users can verify the suffixes on Pocket IE on the go when bus-spotting..
some math:
TIB(4XX) = SBS(25XX/91XX)
TIB(5XX) = SBS(26XX/92XX)
TIB(6XX/10XX) = SBS(XX/27XX/93XX)
TIB(7XX/11XX) = SBS(1XX/28XX/94XX)
TIB(8XX/12XX) = SBS(2XX/29XX/95XX)
TIB(9XX) = SBS(3XX/96XX)
SBS(4XX) = SBS(97XX)
SBS(5XX) = SBS(98XX)
SBS(X - 1000) = TIB(X) = SH(X)
reference suffixes:
SBS 0B, 100X, 200R, 300K, 400E, 500A, 600U, 700P, 800J, 900D, 1000U, 1700H, 1800C, 1900Y, 2000M, 2100H, 2500L, 2600G, 2700B, 2800X, 2900R, 3000G, 3700U, 3800P, 3900J, 7000E, 7100A, 7200U, 9000S, 9100L, 9200G, 9300B, 9400X, 9500R, 9600K, 9700E, 9800A
TIB 0H, 100C, 200Y, 300S, 400L, 500G, 600B, 700X, 800R, 900K, 1000B, 1100X, 1200R -
Wah tamago you very free hor? Thanks. Will run it and check its accuracy.

dun worry, it took only an hour to finish it=) the JavaScript is the more important one as i can double check my regos list with suffixes on the go.. as u can see, the file is veri small and the operative alogrithm (liccheck command) is very easy to do..
for those who know IRC scripting, this is how it goes:
alias liccheck {
/.set %licchk_inputPrefix $1
/.set %licchk_inputNumber $2
/.set %licchk_SBS_CycledOrder ZXTRMKHECAYUSPLJGDB
/.set %licchk_TIB_CycledOrder ECAYUSPLJGDBZXTRMKH
if %licchk_inputNumber isnum 1-9999 {
if ( ( %licchk_inputPrefix == SBS ) || ( %licchk_inputPrefix == TIB ) ) {
if %licchk_inputNumber isnum 1000-9999 {
/.set %licchk_inputNumber1 $mid(%licchk_inputNumber,1,1)
/.set %licchk_inputNumber2 $mid(%licchk_inputNumber,2,1)
/.set %licchk_inputNumber3 $mid(%licchk_inputNumber,3,1)
/.set %licchk_inputNumber4 $mid(%licchk_inputNumber,4,1)
}
if %licchk_inputNumber isnum 100-999 {
/.set %licchk_inputNumber1 0
/.set %licchk_inputNumber2 $mid(%licchk_inputNumber,1,1)
/.set %licchk_inputNumber3 $mid(%licchk_inputNumber,2,1)

if %licchk_inputNumber isnum 10-99 {
/.set %licchk_inputNumber1 0
/.set %licchk_inputNumber2 0
/.set %licchk_inputNumber3 $mid(%licchk_inputNumber,1,1)

/.set %licchk_inputNumberChecksum $calc( %licchk_inputNumberChecksum % 19 )
if ( %licchk_inputNumberChecksum == 0 ) {
/.set %licchk_inputNumberChecksum 19

EXPLANATION:
for e.g. SBS9846, take thousands place times 12 (cos from SBS0 shift by 12 to the right to get suffix of SBS1000, and so on), take hundreds place times 2, take tens place times 11, take ones place times 1, add them up and find the remainder when divided by 19 (number of suffixes in cycled order).. find the corresponding position in the SBS's cycled ordering given above..
1. mutliply each digit by their 'reference' number and add up:
9 * 12 + 8 * 2 + 4 * 11 + 6 * 1 = 174
2. divide by 19 and get remainder.
if it is divisible by 19 exactly, take it as 19.
174 divided by 19, the remainder is 3 ( 9 * 19 + 3)
3. now, SBS's cycled order is "ZXTRMKHECAYUSPLJGDB" (SBS1 is Z, 2 is X etc.) and the 3th alphabet is T.. thus T is the suffix for SBS9846.
REVISION 1:
A bug has been found, related to the fact that 0 remainder does not mean taking 0th alphabet but rather the last (19th) alphabet and an additional 3 lines of code are added.. the old bug meant numbers with suffix "B" had "Z" returned instead for SBS and suffix "H" had "E" returned instead for TIB.. users can download the new text file and overwrite the existing one with mIRC closed (important!)! then you can launch mIRC and use the new revised version.. download it at the same location here..
