Can I use the protruding semicircle on the back of the chip to confirm the 1pin position of the chip?
Is this the only position on the chip package that has the 1pin mark?

Yes, this is one method to determine the pin 1 position. If you have the device in a tape and reel, you can also determine the pin 1 location from this excerpt from the datasheet:
