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:

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.

At Fakecreditcard.co you can easily generate major credit card numbers such as Visa card, MasterCard, American Express, JCB Card and Discover Card.
The credit cards numbers are digits generated based on a mathematical formula that complied with the standard format of the Luhn algorithm (mod 10). The Luhn algorithm formula is used to validate the generation of credit card numbers by using the combination of the BNI (bank identification number) or IIN(issuer identification number) which is mostly about six digits, the account number which ranges from 6 to 9 digits (used to identify the cardholder’s account number) and then the check digit which is the last number added to confirm the authenticity of the credit card.

Generating a credit card number The Luhn algorithm has two basic ways of logically validating the generation of a credit card number in the following ways:

1. When the modulo of the addition of the newly generated credit card number equals to 0, then we would say that the credit card number passes the Luhn algorithm test. Hence, making the generated number valid.
2. When the modulo of the addition of the newly generated number does not equal 0 that is (1-9), then the conclusion that the generated credit card number is invalid since it does not passes the Luhn algorithm test.
