  • First Digit - Major Industry Identifier
  • Six Digit - Issuer identification number
  • Seven Digit - Personal Account Number and Checksum

How Mod 10 or Modulus 10 is Performed on Generating a Valid Credit Card?

The Luhn algorithm or Luhn formula, also known as the "modulus 10" or "mod 10" algorithm, is a simple checksum formula used to validate a variety of identification numbers, such as credit card numbers, IMEI numbers, National Provider Identifier numbers in the United States, Canadian Social Insurance Numbers, Israel ID Numbers and Greek Social Security Numbers (ΑΜΚΑ). It was created by IBM scientist Hans Peter Luhn and described in U.S. Patent No. 2,950,048, filed on January 6, 1954, and granted on August 23, 1960. [source:wikipedia]

Assume an example of an account number "7992739871" that will have a check digit added, making it of the form 7992739871x:

luhn algorithm

The sum of all the digits in the third row is 67+x.

The check digit (x) is obtained by computing the sum of the non-check digits then computing 9 times that value modulo 10 (in equation form, ((67 × 9) mod 10)). In algorithm form:

  1. Compute the sum of the non-check digits (67).
  2. Multiply by 9 (603).
  3. The units digit (3) is the check digit. Thus, x=3.

(Alternative method) The check digit (x) is obtained by computing the sum of the other digits (third row) then subtracting the units digit from 10 (67 => Units digit 7; 10 − 7 = check digit 3). In algorithm form:

  1. Compute the sum of the non-check digits (67).
  2. Take the units digit (7).
  3. Subtract the units digit from 10.
  4. The result (3) is the check digit. In case the sum of digits ends in 0 then 0 is the check digit.

This makes the full account number read 79927398713.
