Check Digit Verification of cas no

The CAS Registry Mumber 1239619-81-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,9,6,1 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1239619-81:
(9*1)+(8*2)+(7*3)+(6*9)+(5*6)+(4*1)+(3*9)+(2*8)+(1*1)=178
178 % 10 = 8
So 1239619-81-8 is a valid CAS Registry Number.

Cinchona alkaloid/TiIV-catalyzed enantioselective enaminetrifluoropyruvate condensation-cyclization reaction and its application to drug-like heterocycles

Ogawa, Shinichi,Iida, Norihito,Tokunaga, Etsuko,Shiro, Motoo,Shibata, Norio

supporting information; experimental part, p. 7090 - 7095 (2010/09/16)

(Chemical equation presented) Drug design: A cinchona alkaloid/Ti IVcatalyzed enantioselective tandem enamine-trifluoropyruvate condensation-cyclization reaction provides a robust method for the construction of small heterocyclic molecules with a quaternary trifluoromethylated carbon center (see scheme). The series of products are attractive templates and were readily converted to drug-like trifluoromethylated heterocycles by conventional methods.
