I think this one should do the trick:
^(?!000|666|9\d{2})\d{3}-\d{2}-\d{4}$
Edit: I find the negative look-ahead syntax in this thread.
Edit 2: Here is a little code snippet for those who want to test it:
import java.util.Scanner;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class Main {
public static void main(String[] args) {
Pattern pattern = Pattern.compile("^(?!000|666|9\\d{2})\\d{3}-\\d{2}-\\d{4}$");
Scanner sc = new Scanner(System.in);
while (true) {
System.out.println("Next number :");
Matcher matcher = pattern.matcher(sc.nextLine());
if (matcher.find()) {
System.out.println("Matches");
} else {
System.out.println("Doesn't match");
}
}
}
}
