Check Digit Verification of cas no

The CAS Registry Mumber 1152853-28-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,2,8,5 and 3 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1152853-28:
(9*1)+(8*1)+(7*5)+(6*2)+(5*8)+(4*5)+(3*3)+(2*2)+(1*8)=145
145 % 10 = 5
So 1152853-28-5 is a valid CAS Registry Number.

Enantioselective and Diastereoselective Construction of Chiral Amino Alcohols by Iridium-f-Amphox-Catalyzed Asymmetric Hydrogenation via Dynamic Kinetic Resolution

Wu, Weilong,You, Cai,Yin, Congcong,Liu, Yuanhua,Dong, Xiu-Qin,Zhang, Xumu

, p. 2548 - 2551 (2017/05/24)

The iridium-f-amphox-catalyzed asymmetric hydrogenation of racemic α-amino β-unfunctionalized ketones proceeds via a DKR (dynamic kinetic resolution) process for the construction of various chiral N,N-disubstituted α-amino β-unfunctionalized alcohols in quantitative yields with excellent enantioselectivities and diastereoselectivities (all products >99% ee and >99:1 dr, TON up to 100 000). Importantly, this catalytic asymmetric hydrogenation with a DKR process provided a highly efficient and powerful synthetic strategy for the preparation of key chiral intermediates of the preclinical antitumor agent (S,S)-R116010.
