MSI Check Digits
With MSI bar codes, one check digit is mandatory and always verified by the reader. The
second check digit is optional. If the MSI codes include two check digits, scan the Two
MSI Check Digits bar code to enable verification of the second check digit.
See MSI Check Digit Algorithm on page 139 for the selection of second digit algorithms.
