Same requirements as this question. But as soon as I try to set the style option, I get this error (Bibliography macro 'site' undefined):
MWE (comment the 3rd line in to reproduce the error):
\documentclass{article}
\usepackage{filecontents}
%\usepackage[style=chem-angew]{biblatex} % fails
\usepackage[]{biblatex}
\DeclareCiteCommand{\supercite}[\mkbibsuperscript]
{\iffieldundef{prenote}
{}
{\BibliographyWarning{Ignoring prenote argument}}%
\iffieldundef{postnote}
{}
{\BibliographyWarning{Ignoring postnote argument}}%
\bibopenbracket}%
{\usebibmacro{citeindex}%
\usebibmacro{cite}}
{\supercitedelim}
{\bibclosebracket}
\begin{filecontents}{test.bib}
@book{A01,
author = {Author, A.},
year = {2001},
title = {Alpha},
}
@book{A02,
author = {Author, A.},
year = {2001},
title = {Alpha},
}
\end{filecontents}
\addbibresource{test.bib}
\let\cite=\supercite
\begin{document}
Citing \supercite{A01, A02}.
\printbibliography
\end{document}
Output without style option:

Ok, turns out that the chem-angew style already does everything, if I would just let it.
The problem was that I originally used style chem-acs, which configures superscript references without brackets, which in turn triggered me to go hunting for square bracket hacks.
Just changing the style to chem-angew was all that was needed:
