more then likely its a black plastic ABS that the glue isn't all that strong. Tap a flat blade screw driver beside the pipe it should have soft yellow glue visible in the joint . basicly your using the screw driver as a wedge , work your way around the entire pipe a few times going deeper each pass. it should split free. If it doesn't your going to need to take down the basement wall and get in there and cut a piece off and coupling new from there up. If it just cracked the bolt flange I think HD has repair kits for the flange in the plumbing section. ABS uses special glue check into what your using first. good luck
