9. (12 points) As shown in the figure, a magician writes down the numbers $1-16$ in 16 positions on a spinning wheel. Four audience members, A, B, C, and D, participate in the magic performance. The magician closes his eyes, and then A selects a number from the wheel, followed by B, C, and D selecting the next number in a clockwise direction. The figure below shows one possible way of selecting the numbers. The magician opens his eyes and says, "Audience members who selected an even number, please raise your hands." At this moment, only A and D raise their hands. The magician then exclaims, "I know the numbers you picked!" What do you think is the product of the numbers chosen by A and D? $\qquad$
【Solution】Solution: According to the problem, we know:
There are 2 odd numbers between 2 even numbers.
It is found that only the numbers $10,11,9,12$ meet the conditions.
The product is $10 \times 12=120$.
Therefore, the answer is: 120
