I like the following one. If that does not work please let me know. I am not an expert in regex but want to become one! 


while (<DATA>)
{
    chomp;
    if (/^(19|20)([5-9]|[0-5])([0-9])$/)
    {
       print "it matches for $_\n";
     }
}
__DATA__
1950
2050
2001
2009
2000

It says: first two digits should be 19 or 20, third digit can go from 5 to 9 or 0 to 5 and the fourth digit is 0-9.
