How many 90 degrees allowed

I am installing a new vanity in my basement. I am using 1 1/2 pvc pipe and the run is less than 5 ft. I need to put either 2 - 90 degree turns or 4 - 45 degree turns to tie into the existing drain in the concrete floor. I have vented this run with 2 in pvc. My question is, is there a limit to the number of 90 or 45 degree turns I am allowed to install in this run? Or is my only concern possible blockage down the road with the 90 degree turns? Thanks in advance for your help.

some codes require 2" vanity drains and as far how many 90's I wouldn't worry about it. Try to use long turn 90's whenever possible. You'll see the difference.
