CRC Calculation of a string of bytes

I need to calculate a CRC based in difference byte value of the data. I have an example but I am not able to get results. I have been looking for CRC online calculators but I don't know how it works. The example that I have is this:

0xA5 0x5A 0x00 0x0A 0x43 0x01 0x25 CRC 0x0d 0x0a

CRC = 0x00 ^ 0x0A ^ 0x43 ^ 0x01 ^ 0x25 = 0x6D

Thank in advance

With only one sample, I can't be sure, but using the online calculator link below, with CRC8_DVB_S2, polynomial 0xD5, the calculated CRC is 0x6D.
