How to split a long string in a variable?

Question

I would like to split a long string (as in the example below) when this string is in a variable:

\documentclass[a4paper]{article}
\def\parametre{0azertyuiopqsdfghjklmwxcvbn1azertyuiopqsdfghjklmwxcvbn2azertyuiopqsdfghjklmwxcvbn3azertyuiopqsdfghjklmwxcvbn}
\usepackage{seqsplit}

\begin{document}

\begin{minipage}{10cm}
\seqsplit{\parametre} %not correct
\end{minipage}

\begin{minipage}{10cm}
\seqsplit{0azertyuiopqsdfghjklmwxcvbn1azertyuiopqsdfghjklmwxcvbn2azertyuiopqsdfghjklmwxcvbn3azertyuiopqsdfghjklmwxcvbn}
%correct
\end{minipage}

\end{document}
