To my knowledge, Apple does not maintain a database of devices such as yours. Your original receipt would contain the serial number.

You don't need to find it in iTunes. If you registered it, Apple will have a reccord of it. If you purchased it from Apple, you can still see about getting a serial for it.
Did you have applecare or anything else attached to it? Or ever call AppleCare at all?
