The standard charge derivation procedure has not changed since forever (i.e.
since the early 1990's). So the tutorial should still be OK, but be sure to
read the caveat there (in bold type).

Why not use R.E.D. Tools itself? That is the most popular way, as far as I
can tell. They maintain a large-ish database that may already have your
ligand, or something close to it.
