9.16 It is known that the number 32※35717※ can be divided by 72, find the digits represented by these two asterisks.
(Kyiv Mathematical Olympiad, 1963)
［Solution］Since $32 ※ 35717 ※$ can be divided by 72, it can be divided by 8 and 9.
If a number can be divided by 8, then the last three digits of this number can be divided by 8. Clearly, the last three digits are 176, which means the last ※ is 6.
If a number can be divided by 9, then the sum of the digits of this number can be divided by 9, that is,
$$
\begin{array}{l}
3+2+※+3+5+7+1+7+6 \\
=34+※ .
\end{array}
$$

Thus, the ※ is 2.
Therefore, the two stars represent the digits 2 and 6, respectively.
