checksum 

Literally, a checksum is a digit used in digital communications that is attatched to the end of the series of other digits to verify the integrity of data.

Some techies may use the word "checksum" as a verb, meaning the act of making sure something they hear about is actually correct instead of simply accepting it as fact.

I usually spend a lot of time checksumming the shit I see on Fox, CBS and NBC.
