When using the LaTeX package url (\usepackage{url} somewhere in the preamble) which tends to give much more nicely formatted web addresses, the following may be preferred:

 @misc{ wiki:xxx,
   author = "Opengenome.net",
   title = "MOPAC --- Opengenome.net{,} ",
   year = "2006",
   url = "\url{http://Opengenome.net/index.php?title=MOPAC&oldid=11202}",
   note = "[Online; accessed 4-February-2026]"
 }
