Is this the correct way to calculate the CRC check code?

But I cannot read the sensor ID via the clock, and the information replied by the sensor seems garbled, regardless of whether I use SPI mode 0 or mode 3. The command I sent is: 0xE180007F. Could you please help me check what the issue might be? Thank you very much for your assistance!
