Check Digit Verification of cas no

The CAS Registry Mumber 216987-05-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,6,9,8 and 7 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 216987-05:
(8*2)+(7*1)+(6*6)+(5*9)+(4*8)+(3*7)+(2*0)+(1*5)=162
162 % 10 = 2
So 216987-05-2 is a valid CAS Registry Number.

The thiolation of pentafluorobenzene with disulfides by C-H, C-F bond activation and C-S bond formation

Liu, Zijian,Ouyang, Kunbing,Yang, Nianfa

, p. 988 - 992 (2018)

A metal-free thiolation reaction between pentafluorobenzene and disulfides by C-H, C-F bond activation and C-S bond formation is reported. Bisthiolated tetrafluorobenzene derivatives would be prepared in moderate to good yields from pentafluorobenzene and disulfides under mild conditions. A possible mechanism for the reaction was given.
