The question as text
A check digit is to be used to validate an identification number on input. The identification number contains five digits and the check digit. The check digit is calculated by adding up the first five digits, dividing by 10 and taking the remainder. For example, 5 + 1 + 2 + 4 + 3 divided by 10 gives a remainder of 5 so the six-digit identification number would be 512435
