Name the following compound using IUPAC rules. Here is a link showing the compound:

Ok, So I know that the order of priority going from the most to least is 1)bromine 2)chlorine 3) fluorine 4) OH 5) H

I am not sure really how to answer this I feel stumped with so many substituents being there. From what I see at first it is moving in the (R) rectus direction but because the bromine is going into the plain and not coming out I assume it is an (S) sinister. Can anyone help explain?

you have to "break" them up at each stereocenter and assess their absolute configuration separately. I drew boxes around each stereocenter in the attachment, treat each on as it's own tetrahedron.
