First, the general public does not have access to the NCIC database of stolen firearms. Second, without more information, we cannot even state what kind of gun that is. A serial number is not unique to only one gun in the world. Your local law enforcement officers may be able to help, but they will want to have the gun in hand when checking it (in case it IS stolen)
No way for us to tell you.
what gun are we talking about here
Contact your local police department and give them the serial number. The Police can check on the stolen gun list maintained by the BATFE. If the gun is stolen, the Police will conficate the piece and begin investigation of how it was acquired.
Contact the police.
Expect the police to expect YOU to explain how you came to possess a gun that had been stolen- just like any other property.
Depends on the DA.
Take it to your local police
Until it is recovered.
Ask a police officer

It is possible.
You need to have the police investigate. there is no website or location that lists all stolen weapons.
