1312945-54-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1312945-54-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,2,9,4 and 5 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1312945-54:
(9*1)+(8*3)+(7*1)+(6*2)+(5*9)+(4*4)+(3*5)+(2*5)+(1*4)=142
142 % 10 = 2
So 1312945-54-2 is a valid CAS Registry Number.

Organocatalytic asymmetric conjugate addition of α-substituted cyanoacetates to maleimides
Wang, Jin-Jia,Dong, Xue-Jiao,Wei, Wen-Tao,Yan, Ming
, p. 690 - 696 (2011)
The asymmetric conjugate addition of α-substituted cyanoacetates to N-substituted maleimides has been developed. A number of cinchona alkaloids and amine thioureas were evaluated as catalysts. Takemoto's catalyst was found to be the most efficient for the
