as always...
Users may view the package catalogue entry at http://www.tex.ac.uk/tex-archive/help/Catalogue/entries/achemso.html or they may browse the package directory at http://www.tex.ac.uk/tex-archive//macros/latex/contrib/achemso
and (as is common) the catalogue entry will change in a small way, overnight.
