Referring to the MERS(Mortgage Electronic Registration Systems), this module uses a mod 10 weight 2 algorithm on a 18-digit string (comprised of a 7-digit organization ID and up to 10-digit loan number) to compute the 18th checksum digit.

The organizaion id + loan number + checksum digit should yield a valid 18-digit MIN(Mortgage Identification Number)
