Given the following numbers: (i) 123456; (ii) 546777; (iii) 456734561883. Solve the following questions for each of the numbers.

(a) Identify the check digit.

(b) Does the number satisfy the checksum?

(c) For the numbers that do not satisfy the checksum, change the value of the check digit so that the new number does satisfy the checksum.

My questions also:

1. The check digit is always the last digit in the number that is given?

2. I am suppose to reverse the numbers writing it from left to right? Then multiply every second number by 2? If its 2 digits when multipled, I add those 2 digits instead? How do I know if that is the correct check digit?
