Check Digit Verification of cas no

The CAS Registry Mumber 111047-52-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,0,4 and 7 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 111047-52:
(8*1)+(7*1)+(6*1)+(5*0)+(4*4)+(3*7)+(2*5)+(1*2)=70
70 % 10 = 0
So 111047-52-0 is a valid CAS Registry Number.

Highly enantioselective aza-henry reaction of ketimines catalyzed by a chiral bifunctional thiourea-tertiary amine derived from quinine

Fang, Yanhong,Lu, Ning,Wei, Zhonglin,Cao, Jungang,Liang, Dapeng,Lin, Yingjie,Duan, Haifeng

, p. 4371 - 4375 (2018)

We have developed a highly enantioselective aza-Henry reaction of aryl α-ketoester-derived N-Ts ketimines with a wide range of substrate scope by a simpler bifunctional thiourea-tertiary amine catalyst derived from quinine. A variety of ketimines were investigated and corresponding products were obtained in excellent yields (up to 99% yield) with excellent enatioselectivities (up to 99% ee).

Organocatalyzed formal [2 + 2] cycloaddition of ketimines with allenoates: Facile access to azetidines with a chiral tetrasubstituted carbon stereogenic center

Takizawa, Shinobu,Arteaga, Fernando Arteaga,Yoshida, Yasushi,Suzuki, Michitaka,Sasai, Hiroaki

supporting information, p. 4142 - 4145 (2013/09/12)

An enantioselective organocatalyzed aza-MBH-type reaction of ketimines and allenoates has been developed. The present formal [2 + 2] cycloaddition produces highly functionalized azetidines with a chiral tetrasubstituted carbon stereogenic center in good to excellent yields and high enantioselectivities.
