Can I see if Live Intro code is registered already without registering it myself first?

[yeebiy]

I bought a used Push 2 from Guitar Center. It came with the box and the insert that has the Live Intro serial code. I would like to sell that code but don't know if it has been registered yet. I don't want to register it because then I can't sell it (unless I go through hassle of a license transfer). But I'd like to find out if it's registered already. Any way to do that?
