AIS2120 CRC and workflow

[Yz2]

uint8_t ubCrcVal(uint32_t ulCrcVal) {
    uint8_t crc = 0x00;
    uint8_t i;
    uint8_t b;
    for (i = 0; i < 4; i++)
    {
        crc ^= (uint8_t) ((ulCrcVal >> (i * 8)));

        for (b = 0; b < 8; b++)
        {
            if (crc & 0x80)
            {
                crc = (uint8_t) ((crc << 1) ^ 0x97);
            }
            else
            {
                crc <<= 1;
            }
        }

int main() {
    uint32_t cmd=0xE1800000; // cmd for sensor id

AIS2120 accelerometer. I'm also using this sensor now and have some questions I'd like to consult with you.Is this the correct way to calculate the CRC check code? I hope to receive your reply. Thank you very much!
