    Java 15:

    import java.io.*;
import java.util.*;
import java.util.regex.Pattern;
import java.util.regex.Matcher;
public class Solution {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        Pattern pattern = Pattern.compile("^[^\\d][^aeiou][^bcDF][^\\r\\n\\t\\f\\s][^AEIOU][^.,]$");
        Matcher matcher = pattern.matcher(scanner.nextLine());
        System.out.println(matcher.find());
    }
}

/*
[^a] means anything other than a
*/
