Ask your client. I know of at least a dozen different algorithms ... None of which use a "X". It might be an inhouse/client developed system.

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?
