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

The Luhn formula or Luhn algorithm , also known as the "mod 10" or "Modulus 10" algorithm, is a simple checksum formula used to validate a variety of identification number, such as credit cards numbers, IMEI numbers, National Provider Identifier numbers in the Usa , Canadian Social Insurance Numbers, Israel ID Numbers & 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, & 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 7992739871xx:

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 mod 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 digit ends in 0 then 0 is the check digit.

This makes the full account numbers read 79927398713.

Do we store these credit cards numbers?
