You can also generate valid credit card numbers for specific Issuing Networks by utilising their particular prefixes. However, we do not provide you (obviously) with the correspondent verification code for these cards, as they are completely fake and made up randomly.

I tried to check the validation of credit card using Luhn algorithm, which works as the following steps: Double every second digit from right to left. If doubling of a digit results in a two-digit number, add up the two digits to get a single-digit number.Sum the results from Step 2 and Step 3. 37 + 38 = 75. If the result from Step 4 is divisible by 10, the card number is valid; otherwise, it is invalid. For example, the number 4388576018402626 is invalid, but the number 4388576018410707 is valid. Simply, my program always displays valid for everything that I input.
