Maybe it's a stupid question but for the verification bytes you're adding the different constants, commands and options. For the sleep that comes out to 0x173 (as you also wrote down). Why is the higher verification byte then 0x73 and not 0x173? Or is it a typo?

0x173 doesn't fit in a byte. As the text explains, there are two validation bytes; the first one gets the high 8 bits ("the high byte") of 0x173 (which is 0x01) and the second one gets the low eight bits (0x73).
