touchback - (American football) a play in which the opposing team has kicked the football into your end zone.
From Wikipedia, the free encyclopedia. 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.
Locating Your Routing Number. You can find the bank routing number, your checking account number and the check number (in that order from left to right) located at the bottom of one of your checks. See the above example. Make sure you are using a check and NOT a deposit slip, since the numbers may not be the same. The first nine numbers from the left at the bottom of your check are your bank routing number. This number is always nine digits.
