It validates the frame data and would need to determine if the frame had been damaged after transmission.

The FCS field contains a number that is calculated by the source node based on the data in the frame. This number is added to the end of a frame that is sent. When the destination node receives the frame the FCS number is recalculated and compared with the FCS number included in the frame.

So FCS must be in the trailer.
