288074-12-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 288074-12-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,8,0,7 and 4 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 288074-12:
(8*2)+(7*8)+(6*8)+(5*0)+(4*7)+(3*4)+(2*1)+(1*2)=164
164 % 10 = 4
So 288074-12-4 is a valid CAS Registry Number.

Quinine-catalyzed enantioselective tandem conjugate addition / intramolecular cyclization of malononitrile and 1,4-dien-3-ones

Hu, Zhi-Peng,Li, Jian,Yin, Xiao-Gang,Zhang, Xue-Jing,Yan, Ming

, p. 1 - 13 (2013/04/10)

An organocatalytic tandem conjugate addition / intramolecular cyclization of malononitrile and conformationally restricted 1,4-dien-3-ones has been developed. A series of cinchona alkaloids and their derivatives were examined as the catalysts. Quinine was

Organocatalytic conjugate addition of malononitrile to conformationally restricted dienones

Hu, Zhi-Peng,Lou, Chun-Liang,Wang, Jin-Jia,Chen, Chun-Xia,Yan, Ming

experimental part, p. 3797 - 3804 (2011/07/08)

Organocatalytic conjugate addition of malononitrile to conformationally restricted dienones has been studied. A series of chiral primary and tertiary amine catalysts were screened. A piperidine-based thiourea-tertiary amine was found to be the efficient c
