You could use a look-ahead.
use strict;
use warnings;
my @nos = qw{
12304500
123
1234567000000
987045027000
};
print
map { sprintf qq{%15s : %5s\n}, @$_ }
map { [ $_, m{(\d{1,5})(?=0*\z)} ] }
@nos;
Here's the output.
12304500 : 23045
123 : 123
1234567000000 : 34567
987045027000 : 45027
I hope this is of use. Cheers, JohnGG
Update: No, that doesn't work unless you make the \d{1,5} non-greedy, as suggested by duff

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
