Re^3: How to write a regular expression to extract a number from an embedded string?

No, it isn't. I'm allowing (optional) whitespace before the digits, but it's not counting. Look again at the part that says

(?:\s*\d){8}

That is, exactly 8 occurences of (any number of spaces followed by) a single digit. What my code did do wrong is that it assigned $numbers to the result of the check in scalar context, not in list context. But

my ($numbers) = $string =~ /(5163(?:\s*\d){8})/;

will work. If you don't believe me, test it out.
