eancheck - check digit validator for EAN, PLU and UPC barcode numbers
eancheck [EAN code, PLU code or UPC prefixed with 0]
eancheck takes a 13 digit EAN (European Article Number, aka a barcode number) or a 4 digit
PLU code and runs some simple maths upon it to discover the "check digit". It then
compares this against the last number of the inputted EAN to check whether that code; if
they match, then the EAN/PLU is valid. If they do not, then the opposite applies.
