What do you mean by this? Why would you hash it further? Hash distribution is primarily down to the hashing algorithm, not the input data.
Also indexes are better with somewhat ordered and smaller data. A 64-bit int sequential counter is much faster and half the size, and compatible everywhere without the annoyances of a UUID.
