Easiest way to check would be to just hook it up and see if it works. Unplug immediately if you see smoke, smell something, see something melting, see sparks, etc.
In reality, though, circuits don't tend to blow up. You may melt a resistor or blow a capacitor (if voltage rating is too low), but as long as you keep the input voltage in check (like from a battery), it's almost impossible to damage chips (at least the ones you are using).
