my support profile, apple idea to retrieve serial number of stolen product

My computer was stolen this evening and I have no way of getting the serial number to have it tracked...Is there anyway that I can find it through support online from another computer? It was registered but not password protected and not under insurance. I'm hoping to get the serial number through apple, but can't find it in the suports section and they say they can't track it over the phone. I just want some chance of getting it back if it turns up on craigslist or dropped at a pawn shop... Any and all suggestions are appreciated!!
