Check Digit Verification of cas no

The CAS Registry Mumber 82943-20-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,9,4 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 82943-20:
(7*8)+(6*2)+(5*9)+(4*4)+(3*3)+(2*2)+(1*0)=142
142 % 10 = 2
So 82943-20-2 is a valid CAS Registry Number.

(Perhalomethylthio)heterocycles, XIV. Preparation and Properties of N-Substituted Tetrakis(trifluoromethylthio)pyrroles

Ceacareanu, Dumitru M.,Gerstenberger, Michael R. C.,Haas, Alois

, p. 3325 - 3331 (2007/10/02)

2,3,4,5-Tetrakis(trifluoromethylthio)pyrrole (1) reacts with bases and Lewis bases to give salts and 1:1 adducts, respectively.The potassium (2b) and sodium salt (2c) as well as the adducts of pyridine (2d), NH3 (2e), and trimethylamine (2f) were prepared.Reactions of the silver or potassium salts with sulfenyl chlorides or SxCl2 (x = 1,2) give N-sulfenylated pyrroles 6a-f as well as dipyrrolylsulfane 5a and -disulfane 5b.Pentakis(trifluoromethylthio)pyrrole (6a) is a good mild sulfenylating agent, exchanging the CF3S group for acidic hydrogen atoms in alcohols, thioalcohols and amines.The silver salt 2a reacts with CF3SeCl to form 1-(trifuoromethylselenyl)-2,3,4,5-tetrakis(trifluoromethylthio)pyrrole (6g).Except 2a,d,f all other substances are sensitive against hydrolysis.
