in thread repeatedly delete words expressed in alternation from end of string [regexp]

Should only remove the expression from the end of the string. So it's actually a little simpler: 
my @words = qw( SA NV LTD CO LLC );
my ($re) = map qr/$_/i, join '|', map quotemeta, @words;

while (<DATA>) {
  chomp;
  s/(?:\s*\b$re)+$//;
  print "[$_]\n";
}
__END__
