Do you have the patent number without decimal point?

the format of the patent number is xxxxxxxxxxxx.x. The first four digits are the year, such as 215, and the serial number behind the patent type 1 2 3 8 9 is from 1 to 9999999. The dots and numbers behind it are check codes, which are similar to the last digit of an ID card. Generally, if it is -9, it is the number obtained by a complicated algorithm, which is used to check whether your patent number is correct, so it will definitely be available.
