Explanation:
Detailed explanation-1: -A check digit is a form of redundancy check used for error detection on identification numbers, such as bank account numbers, which are used in an application where they will at least sometimes be input manually. It is analogous to a binary parity bit used to check for errors in computer-generated data.
Detailed explanation-2: -The last digit of a barcode number is a calculated check digit. The check digit is calculated from all the other numbers in the barcode and helps to confirm the integrity of your barcode number.
