Hi
We have a client who is using a Docket numbering system that incorporates a check "digit" at the end. The check "digit" is 0-9 or x.
thus: 399079x, 3990800, 3990811
The purpose of the check digit is to verify the validity of the digits in the root number - a sequence of digits in the root number can have only one valid check digit.
I suspect that this is a common device, and if it is, I am wanting to know what the algorithim is to determine the check digit from the root number.
Anyone any ideas?
Thanks
