I am thinking of a number

I am thinking of a number between 1 1 and 1 0 5 10^{5} (inclusive) that is a palindrome. Let this number be N N . All of the following are true:

{ N m o d 11 = 1 N m o d 17 = 13 N m o d 23 = 16 \begin{cases} N \bmod 11 = 1 \\ N \bmod 17 = 13 \\ N\bmod 23 = 16 \end{cases}

What is N N ?


The answer is 12321.
