A - A water problem HDU - 5832

Two planets named Haha and Xixi in the universe and they were created with the universe beginning. 

There is 7373 days in Xixi a year and 137137 days in Haha a year. 

Now you know the days NN after Big Bang, you need to answer whether it is the first day in a year about the two planets.

Input

There are several test cases(about 55 huge test cases). 

For each test, we have a line with an only integer N(0≤N)N(0≤N), the length of NN is up to 1000000010000000.

Output

For the i-th test case, output Case #i: , then output "YES" or "NO" for the answer.

Sample Input

10001
0
333

Sample Output

Case #1: YES
Case #2: YES
Case #3: NO
