aix shell 字符串

请教大家个问题：
我想写这样的判断，如果comid 在（5100,1200,3302,3400,3600,4500）这个集合里面。if这一段代码还没有比较简洁的写法，谢谢。

comid=$1
if [[ ${comid} == '5100' ]] || [[ ${comid} == '1200' ]] || [[ ${comid} == '3302' ]] || [[ ${comid} == '3400' ]] || [[ ${comid} == '3600' ]] || [[ ${comid} == '4500' ]]
then
echo " #######";
else
echo "$$$$$$$$$$$$$$$$$"
