Not completely sure what you want here, but you don't get a "mama" because none of the strings you are matching against are isolated by spaces (e.g. you get 1696-R2.2 not 1696) and even if that wasn't a problem, the case matching will fail as well (e.g. 162x <> 162X).

Here's some code that does something - whether it's what you want, or whether it gives you some ideas how to get what you want I leave up to you

my $data_file = 'diana.txt';
my @identifiers = qw(1696 162x 1640);
open(FILE, $data_file) || die("Could not open file: $!");
foreach $line(<FILE>){
  chomp $line;
  foreach $identifier(@identifiers){
    if($line =~ /$identifier/i){
      print "$line match\n";
    }
  }
}
close FILE;
