Will the gear tooth break?

2 small CIMs, with a 12 tooth gear on each that mate with a single 45 tooth gear on a separate shaft. On the same shaft as the 45 tooth gear is a 13 tooth gear. These gears are 20 pitch, 14.5 degree pressure angle, and 3/8" face width. For now, let's say the 13 tooth gear is made out of common cold rolled steel.

Assuming a worst case scenario (motors reach stall torque/current), will the 13 tooth gear be able to withstand the force?

What calculations are used for this?
