Arggh, I went to fix a bug and accidentally deleted the whole post.

No need for modules

use strict;
use warnings;

my $limit = 987654321;
my $magic_num = 9 * 8 * 7;
my $max = int ($limit / $magic_num);
my $start = $max * $magic_num;

for (0..$max - 1){
    my $num = $start - $magic_num * $_;
    next if $num =~ /[05]/;
    next if $num =~ /(.).*\1/;
    die "$num\n"
}
