Hello, all.

Does anyone know of a CFC that can take a string and return whether that string is a UPC, an EAN, or an ISBN?

I'm working on a site that adds items to a seller's half.com account (for many sellers) and the product ID that is being supplied could be a UPC, an EAN, or an ISBN (both -10 and -13), and I need to be able to tell half.com which the product ID is.
