The last digit of each credit card is the number of examination or test number, which is used to validate the credit card using the Luhn algorithm that will explain it now with detail
Used algorithm Luhn to ensure the validity of all types of figures, including credit card numbers, social security numbers, ID numbers global mobile, which is not designed to be secure against cryptographic hash, but simply a way to make sure no additional errors during registration numbers, Here's how to make sure a certain number is correct by using this algorithm:
Type the number of your credit card, then "from right to left," then the second to double the number of each digit and write output down this figure, in the third line we write the numbers that we have not double it as they are, but the numbers doubled If less than 9 we write as it is but if was greater than 9're bringing the number 9 of them and write the output under number as shown in the picture

The final step is to collect the numbers in the third line if the resulting number is divisible by 10 numbers are correct
