When you have passed your Phd with no corrections that is a significant achievement and yes of course you would put it on your CV because it might be the difference in getting the interview. If you had a 1st class honours degree or distinction you would put this on your CV for the same reasons. When you pass your PhD at the University I attended the school/department always email everyone staff/postgraduates who has passed and whether they have corrections. They also state PhD student who don't have corrections and that it is a significant achievement. So do put it on your CV..no one is ever going to ask you and if you don't put it on your CV then you might just miss out on the interview
