You went into the computer business in 1965? Please tell me you bought shares in IBM!

The format was CNNNNNX where N is a digit and X is a checksum letter. - AA

In which case, I suspect that one of your Ns is missing......

My number was W1941305 (Total 23)

Using Tinribs system, Post 91, it is correct. (A=1 etc) so (W=23)

Using Ricardian´s algorithm and discarding O and I the number calculated is 17 which corresponds to T

Help!!!

1 X 8 = 8
9 X 17 = 153
5 X 4 = 20
0 X 16 = 0
3 X 2 = 6
8 X 13 = 104
5 x 5 = 25
Total = 316(A) / 23 = 13(.73913) x 23 = 299(B)
(A)316 – (B)299 = 16 = Letter S

My letter is W! Where have I gone wrong?

Unfortunately not. In those pre-Thatcher days of exchange controls, one had to pay a premium for 'investment dollars'. The buyer was taking a bigger risk on the exchange fluctuations that the underlying investment.

I don't own this space under my name. I should have leased it while I still could

TTN, last weekend in September to get a slightly better weather, doesn't always work. Organised by the Guernsey Association RN and RM, used to include RM band until MOD withdrew its support after the 70th, a C d'Honour at Government House, RNLI to a ceremonial wreath laying, a church service and a March to the cemetery with Salvation Army, St John's Ambulance, Police etc. The RN still tries to send a Guardship even though MOD does not support it.

ricardian's algorithm certainly wasn't the one used in the 1990s. With that algorithm, the letter will advance by 5 every time the number goes up by one, and by 14 every time the tens digit ticks over (e.g. xxxxx59 to xxxxx60). But in numbers from my era, the letter advances by 1 per number, or 4 when the tens digit ticks over.

2....58J
2....59K
2....60P
2....61Q

etc.

Aaron O D,

I believe at one time ACM Sir Patrick Hine became Fg Off Hine RAFVR(T) while he was an AEF pilot....

Saluted Paddy Hine coming out of the Mess at Coltishall by mistake. He was wearing Fg Off rank tabs and I was a Flt Lt at the time.

Don't leave us in suspense, Megaton - what was his mistake?

Jack

PS I bet he was wearing or carrying his Air Officer's hat

A slight change to the algorithm fixes it. Multiply the last digit by 1 (not 5), discard "I" and "O" in the alphabet and start at zero when counting through.

This works for all examples in the thread.

Service Number
1941305

1x8=8
9x17=153
4x4=16
1x16=16
3x2=6
0x13=0
5x1=5

A= 204
B= 184
A-B= 20

ABCDEFGHJKLMNPQRSTUVWXYZ (Starting with A=0)

Checkdigit W

Yes, works for mine and others. Although in maths terms, the last few sentences can simply be replaced with "A modulo 23".

For starters 316 - 299 isn't 16

This esoteric arithmetic....

.....is all very well but has there been an outcome from the original poster? Was the chap a wrong 'un or not? I feel we should be told.

Sorry, too interested in all the codebreaking. I've just realised that as well as I and O, Z is also omitted (hence the use of modulo 23), so A follows Y, unless Y was suffixing a number ending in 9, in which case the next letter is D.
