1372768-23-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1372768-23-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,2,7,6 and 8 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1372768-23:
(9*1)+(8*3)+(7*7)+(6*2)+(5*7)+(4*6)+(3*8)+(2*2)+(1*3)=184
184 % 10 = 4
So 1372768-23-4 is a valid CAS Registry Number.

Hybrid metal/organo relay catalysis enables enynes to be latent dienes for asymmetric diels-alder reaction

Han, Zhi-Yong,Chen, Dian-Feng,Wang, Ya-Yi,Guo, Rui,Wang, Pu-Sheng,Wang, Chao,Gong, Liu-Zhu

, p. 6532 - 6535 (2012/06/15)

The hybrid Au(I)/Bronsted acid binary catalyst system enables enynes to serve as latent 1,3-silyloxydienes capable of participating in the first cascade hydrosiloxylation of an enynyl silanol/asymmetric Diels-Alder reaction. A variety of polycyclic compounds bearing multistereogenic centers were obtained in high yields and excellent enantioselectivities from the relay catalytic cascade reaction between (2-(but-3-en-1-ynyl)phenyl) silanols and quinones catalyzed by the combined achiral gold complex and chiral N-triflyl phosphoramide.
