If as stated earlier you are looking for the first match that is a doubled number, I would do it like this: 
#!/usr/local/bin/perl -w

use strict;

my $var        = '77373737377837';

my @new_var    = $var =~ /((\d)$1)/;
my $var2       = join('', @new_var);

Please next time try to phrase your question more clearly.
