This paper deals with protection of banknotes and it introduces a less known algorithm used to protect former German banknotes which is a special mathematical model used for their numbering. This model, based on a check digit, may be suitable as a protection against counterfeiting of official documents such as university diplomas, certificates, driving licences etc.
