We cannot look up Apple serial number history any more that you. We are end users too.
You can enter the number into this Apple support page from another device:
Check Your Service and Support Coverage
and determine if the device shows eligibility for coverage including AppleCare. Not definitive, but shols is say the device is ineligible, that is pretty much positive proof of problem.
However, I concur with my wise colleague that buying from a non-Apple source is fraught with frustration and potential financail harm. Most complaints here about discovering the device being pre-owned and cannot be activated started with exaclty what you are trying to do.
The massive world-wide demand for Apple products has created fertile ground for shady sellers. Don't fall into the pit!
