Figure . The same digraph as in Figure , for VS242, here also indicating the four pseudoasymmetric centers. In this case, sorting and listing of ligands gives different results after application of Rule 4c, which sorts both main ligand branches by r > s. The Rreference, Ligand A, with RSRSR… has higher priority than B, with RSRSS…. Due to the fact that both asymmeric ligands are their own enantiomorph, the final designation is R rather than r.
