I try to simulate some embedded protocol, I can't find which check sum algorithm it use. Is there any other algorithm? -

length|data0|data1|data2|data3|data4|data5|data6|data7|checksum| 9     |3    |41   |0    |70   |77   |55   |32   |0    |205     | 9     |3    |41   |0    |70   |77   |54   |32   |0    |206     | 

i familiar brc,crc,lrc, no 1 works, there other common algorithm in embbeded?

additional info:

length  data0   data1   data2   data3   data4   data5   data6   data7   data8   data9   data10  data11  data12  data13  data14  data15  data16  checksum 18      3       38      1       0       1       11      16      57      48      46      51      32      77      72      122     0       0       56 18      3       38      1       0       1       11      16      57      50      46      50      32      77      72      122     0       0       55
