Check Digit Verification of cas no
The CAS Registry Mumber 57381-56-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,3,8 and 1 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 57381-56:
(7*5)+(6*7)+(5*3)+(4*8)+(3*1)+(2*5)+(1*6)=143
143 % 10 = 3
So 57381-56-3 is a valid CAS Registry Number.

The preparation of trifluoromethyl aryl sulfides using KF and thiophosgene
Clark, James H.,Tavener, Stewart J.
, p. 169 - 172 (2007/10/03)
The trifluoromethanethiolate anion may be generated in situ by the reaction of thiophosgene with potassium fluoride in acetonitrile. This system is used to prepare trifluoromethyl aryl sulfides from activated fluoro- and chloroaromatic substrates via nucleophilic substitution.
