这看起来像是 CRC （具体来说它看起来像CRC-16-CCITT，由诸如802.15.4，X.25，V.41，CDMA，蓝牙，XMODEM，HDLC，PPP和IrDA）。你可能想阅读关于链接到***页面的CRC理论，以获得更多的见解。或者，您可以将其视为黑盒，只是解决计算校验和的问题。

This looks like a CRC (specifically it looks like CRC-16-CCITT, used by things like 802.15.4, X.25, V.41, CDMA, Bluetooth, XMODEM, HDLC, PPP and IrDA). You might want to read up on the CRC theory on the linked-to Wikipedia page, to gain some more insight. Or you can view this as a "black box" that just solves the problem of computing a checksum.
