Jmol 14.15.2 https://sourceforge.net/projects/jmol/files

fully implements all IUPAC 2013 Blue Book (
http://pubs.rsc.org/en/content/ebook/9780854041824) involved in:

   -- simple R/S and E/Z, with small-ring removal of E/Z
   -- odd and even cumulenes (E/Z, M/P)
   -- atropisomers (M/P)
   -- pseudochiral r/s and m/p
   -- P, S, As, Se, Sb, Te, Bi, Po trigonal pyramidal and tetrahedral
   -- imine and diazine E/Z chirality

(In case "M/P" is new to you,  M(inus) and P(lus) are the preferred
designations now for axial and planar chirality rather than Ra and Sa,
respectively. I like this a lot, because it is simply the sign of the
associated torsion angle.)

Jmol does not implement hypervalent chirality (trigonal bipyramidal,
octahedral)

If nature does not answer first what we want,
it is better to take what answer we get.
