Check Digit Verification of cas no

The CAS Registry Mumber 1301740-46-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,1,7,4 and 0 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1301740-46:
(9*1)+(8*3)+(7*0)+(6*1)+(5*7)+(4*4)+(3*0)+(2*4)+(1*6)=104
104 % 10 = 4
So 1301740-46-4 is a valid CAS Registry Number.

Br?nsted acid-catalyzed synthesis of diarylmethanes under non-genotoxic conditions

Mendoza, Oscar,Rossey, Guy,Ghosez, Léon

experimental part, p. 2235 - 2239 (2011/05/05)

Triflic acid and triflimide were found to efficiently catalyze the formation of a wide diversity of diarylmethanes from the non-genotoxic benzylic acetates and electron-rich arenes or heteroarenes. The reaction worked best with acetates capable of generating a stabilized benzylic cationic species. In most cases, the reactions were conveniently run in the absence of solvent under mild conditions.
