macro_rules! read_line {
    () => {{
        let mut input = String::new();
        std::io::stdin().read_line(&mut input).unwrap();
        input
    }};
}
fn read_and_parse<T: std::str::FromStr>() -> T {
    read_line!().trim().parse().ok().unwrap()
}
fn main() {
    let x: i32 = read_and_parse();

    if x % 10 == 7
        || x / 10 % 10 == 7
            || x / 100 % 10 == 7 {
        println!("Yes");
    } else {
        println!("No");
    }
