Check Digit Verification of cas no

The CAS Registry Mumber 1400999-68-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,0,9,9 and 9 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1400999-68:
(9*1)+(8*4)+(7*0)+(6*0)+(5*9)+(4*9)+(3*9)+(2*6)+(1*8)=169
169 % 10 = 9
So 1400999-68-9 is a valid CAS Registry Number.

Oxytrifluoromethylation of multiple bonds using copper catalyst under mild conditions

Egami, Hiromichi,Shimizu, Ryo,Sodeoka, Mikiko

supporting information, p. 5503 - 5506 (2012/11/07)

Oxytrifluoromethylation reaction of styrene derivatives and alkynes with external and internal oxygen nucleophiles, catalyzed by copper (I) salts under mild conditions, was developed. Direct formation of a β- trifluoromethylstyrene derivative from a styrene derivative was also achieved by the reaction in the presence of a Bronsted acid. Further transformation of the oxytrifluoromethylated products was conducted to demonstrate their utility. 2012 Elsevier Ltd. All rights reserved.
