What is LHUN Algorithm?
How to check the valid credited card using LHUN.

Ex:       1 2 5 4   - 1 2 3 4 - 1 2 3 4 - 1 2 5 4

            4 5 2 1 - 4 3 2 1 - 4 3 2 1 - 4 5 2 1

                  6     +       4      +     4   +     6

                              = 20

If(20/10==0)
It is a valid card Process?

Is that one is right justify how?

If you mean the Luhn algorithm (named after its inventor, Hans Peter Luhn) then check out this article for details of how it works:

There's a link to a Luhn validation class, written in C#, at the foot of this article.
