Hey Hi Priyanka patel,


Here is I came across a link where you can actually check whether your Credit card Number is valid or not. 


How to check the validity of your card?

You can check whether your credit or debit card is really valid or not by following the steps mentioned below. Take, for example, the card number: 4417 1234 5678 9113


Step 1: Start from the right side and separate all the even and odd digits.


4417 1234 5678 9113


41 13 57 91 47 24 68 13


Step 2: Double all the digits in the first set


82 26 (10)(14) (18)2


Step 3: Add all double digit numbers as the sum of their digits.


82 26 (1+0)(1+4) (1+8)2


82 26 15 92


Step 4: Add all the odd digits (those that have not been doubled) to the even (doubled) digits.


8 + 2 + 2 + 6 + 1 + 5 + 9 + 2 + 4 + 7 + 2 + 4 + 6 + 8 + 1 + 3 = 70


Step 5: Final result – If the final result is divisible by 10, the card number is valid.


70/10=7 (The number is valid)
