OGM

Library to generate and validate Belgian OGM's.

An OGM is a Belgian format used to automatically identify payments. The typical structure of an OGM is +++090/9337/55493+++ or ***090/9337/55493***. In total the OGM contains 12 digits. A group of 3, 4 and 5 digits separated by /, and starting and ending with '+++' or '***'. The last 2 digits of a valid OGM is the remainder of the euclidean division of the first 10 digits of the OGM and 97. When the remainder is 0, the last 2 digits are 97. Wikipedia (Dutch)
