Whenever you think about "remove duplicates" in Perl, think hashes. In this case, you probably want to have each hash entry be an array containing the numbers:

my %data;
while(<>) {
    chomp;
    my ($name, $number) = $_ =~ /\A (\D+) (\d+) \z/x;
    push @{ $data{$name} }, $number
        if $name && $number;
}
