Perl regex question

I have the following code:

Code:
#!/usr/bin/perl -w

@files = <*.csv>;
foreach $file (@files) {
  open(FH, $file) || die("Error: Cannot open file $file for reading.");
  my @dt = ($file =~ /^(\w+).(\d{6})\.csv$/);
  while (<FH>) { 
    print "@dt[0] $_\n";
  }
  close(FH);
}

There is redundancy in this code as it first checks for all files ending in ".csv" (line 3) and subsequently parses the filename (line 6) looking for characters and digits. How do I change line 3 into a regular expression, such that line 6 can be removed and the array @dt be determined there?
