Solving the bibtex problem with underscores in DOI

Have you had problem with compiling Latex files when there was an underscore in the DOI number of one of citations. Usually, it ends up with an error similar to this:

! Missing $ inserted.
<inserted text>
                $
l.286   {\path{doi:10.1001/001-1-11-111-1_11}}


The solution is to call the underscore package:

\usepackage[strings]{underscore}
