Check Digit Verification of cas no

The CAS Registry Mumber 221155-02-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,1,5 and 5 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 221155-02:
(8*2)+(7*2)+(6*1)+(5*1)+(4*5)+(3*5)+(2*0)+(1*2)=78
78 % 10 = 8
So 221155-02-8 is a valid CAS Registry Number.

Palladium-catalyzed asymmetric intermolecular Mizoroki-Heck reaction for construction of a chiral quaternary carbon center

Zhang, Qing-Song,Wan, Shi-Li,Chen, Di,Ding, Chang-Hua,Hou, Xue-Long

, p. 12235 - 12238 (2015)

Palladium-catalyzed asymmetric intermolecular Mizoroki-Heck reaction for the construction of a chiral quaternary carbon center is developed, affording 2,2-disubstituted 2,5-dihydrofurans in high yield with excellent enantioselectivity. The products are ea

Chiral silver phosphate-catalyzed cycloisomeric kinetic resolution of α-allenic alcohols

Wang, Yan,Zheng, Kuan,Hong, Ran

, p. 4096 - 4099 (2012/04/10)

A kinetic resolution of α-allenic alcohols is realized through chiral silver phosphate-catalyzed cycloisomerization with high stereoselectivity (selectivity factor up to 189) and tolerance of a variety of functional groups. A mechanistic model is proposed to interpret the origin of the high stereoselectivity and broad substrate scope.
