type digit incorrectly & "checksum" does not tally.
Just a thought as I'm now in IT & we use checksums a lot for part stock numbers etc
Mine was P/092682X then they changed it to D/ why that, remember it causing great confusion at the time, and just out of interest what is the current O/No being issued to those poor unsuspecting boys.Nicks said:Ive been out for 25 years now but one thing I never got round to asking is,
What does the letter at the end of your official number stand for?
I was D144806T.
Whats the T stand for please??

PompeySailor said:Yep - it's a checksum. No, I've forgotten the formula, despite writing the code for it.....! Seriously. I know is has something to do with not using all the letters in the alphabet, assigning a numeric value to them, and multiplying the numbers in your service number to come to a "remaindered" number. If I have a lucid flashback, I will post the exact answer!
