1321619-39-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1321619-39-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,2,1,6,1 and 9 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1321619-39:
(9*1)+(8*3)+(7*2)+(6*1)+(5*6)+(4*1)+(3*9)+(2*3)+(1*9)=129
129 % 10 = 9
So 1321619-39-9 is a valid CAS Registry Number.

Highly efficient construction of trifluoromethylated heterocycles; [3+2] annulation of N,N′-cyclic or C,N-cyclic azomethine imines with trifluoromethyl-containing electron-deficient olefins

Wang, De,Deng, Hong-Ping,Wei, Yin,Xu, Qin,Shi, Min

, p. 401 - 406 (2013)

A highly regio-and stereoselective synthesis of pyrazolidine analogues by the use of N,N′-cyclic or C,N-cyclic azomethine imines with two different trifluoromethyl-containing olefins has been developed. The method affords highly functionalized trifluorome
