Whether your pattern is correct or depends on what you want to achieve:
- if you want to match a single digit or letter followed by a dash and
a number uf digits for the id, then your pattern is correct.
- if you want your pattern to macht the url you have given, then its
not correct.

You want something like this (untested):

url(r'^([a-zA-Z0-9\-]+-(?P<nid>\d+).html$', 'tempa')

And that only matches lower- and upper-case letters, numbers and
dashes. If you want to allow any non-ascii characters you might want
something different in that first parantheses.

Have fun,
