To avoid the costly overhead of manually correcting rejected Bacs payments, Faster Payments or Direct Debit, all bank account details should be checked.To reduce the possibility of such mistakes, account numbers can be crafted in such a way that simple errors are detected.This is done by calculating a single-digit value based on the account number, and then appending that digit to the base number to arrive at a final account number.You should later compare the old value of the check-bit, with the new to ensure the VIN's validity.Transliteration consists of removing all of letters and substituting them with their appropriate numerical counterparts. The following is the weight factor for each position in the VIN. It has been substituted with a 0, which will cancel it out in the multiplication step. Straight-ones (seventeen consecutive '1's) will suffice the check-digit. Each digit in the base number is assigned a multiplication factor.

The factors are assigned from right to left, starting at two and counting up.

One common scheme for generating self-check digits, described here, is called Modulus 11 Self-Check.

There are various versions of this, which differ in the weightings used; this document describes the one used by IBM on the i Series (formerly AS/400, System/38) and in the 5250 series of terminal devices.

Calculating the Check Digit Understanding the Background and Development of the Numbering System Understanding How Banks Use Routing Numbers Community Q&A The routing number on a check uniquely identifies the financial institution and the location where the check was printed.

Financial institutions use routing numbers to instantaneously process financial transactions.
