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

The Luhn algorithm , also known as the Modulus 10 algorithm, is a simple checksum formula used to validate a variety of identification number, such as credit card numbers, IMEI numbers, National Provider Identifier numbers in the Usa and Canadian Social Insurance Numbers, Israeli occupied ID Numbers and (ΑΜΚΑ) Greek Social Security Numbers . It was created by International Business Machines 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]

Suppose an example of an account number "7992739871" to which a check digit will be added, making it from the form 7992739871xx:

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

The control digit (x) is obtained by calculating the sum of the non-control digits and then computing 9 times that mod 10 value (in the form of an equation, ((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 control digit (x) is obtained by calculating the sum of the other digits (third row) and then subtracting the digit from the units of 10 (67 => digit of the units 7 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. if the sum of the digit ends in 0, then 0 is the control digit.

This makes the full account numbers read 79927398713.

Do we keep these credit card numbers?

of course not! The numbers of credit cards entered in our validator were subjected to a process that uses validation rules. However, we do not store these credit cards for security reasons.

Is this online verification tool safe to use?

Yes! Our validator only checks the ID of the main industry or MII, the personal account numbers and the issuer identification number. please read the detailed table for "MII "below.

The first digit of the credit card number is the Major Industry Identifier "MII", which represents the category of entity who issued your credit card. Different MII digits represent the following emitter category :

For example, Diner's Club,American Express, and Carte Blanche are in the travel and entertainment category, VISA, MasterCard, and Discover are in the banking and financial category, and SUN Oil and Exxon are in the petroleum category.
