I want to check whether the patent number is true.

This is definitely not a patent number. The format of patent number should be: 200930 167308.5.

The patent number consists of year, patent type and serial number. The number after the year in the patent number is only 1 or 2 or 3, where 1 stands for invention, 2 stands for utility model and 3 stands for appearance patent.

In addition, this number is only 7 digits, which is definitely not the patent number.
