The Check Digit Modulus is 10. It passes because 60 is divisible by 10 (the remainder is 0).
Digit Add Left to Right
Each character in the scanned data is assigned a numeric value (see OCR Check Digit Multiplier on page 329).
Each value representing a character in the scanned data is multiplied by its corresponding digit in the multiplier,
resulting in a product for each character in the scanned data. The sum of each individual digit in all of the products
is then calculated. The check digit passes if this sum modulo Check Digit Modulus is zero.
Example:
Scanned data numeric value is 132456 (check digit is 6)
Check digit multiplier string is 123456
Digit 1 3 2 4 5 6
Multiplier 1 2 3 4 5 6
Product 1 6 6 16 25 36
Digit add 1+ 6+ 6+ 1+6+ 2+5+ 3+6= 36
The Check Digit Modulus is 12. It passes because 36 is divisible by 12 (the remainder is 0).
