Check Digit Verification of cas no

The CAS Registry Mumber 1152957-31-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,2,9,5 and 7 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1152957-31:
(9*1)+(8*1)+(7*5)+(6*2)+(5*9)+(4*5)+(3*7)+(2*3)+(1*1)=157
157 % 10 = 7
So 1152957-31-7 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.

Paragraph 0029; 0030, (2017/02/28)

The invention discloses a copper bromide reagent, a preparation method thereof, and a synthesis method of alpha-amido propiophenone and derivative thereof. Copper bromide cheap in industry and 2,6-bi[4-(1,1-dimethyl)-2-oxazoline-2-base] pyridine react to directly obtain high yield of high-purity copper bromide reagent, in addition, the copper bromide reagent and propiophenone containing multiple important functional groups have good reaction activity. Due to the characteristic, high yield of alpha-amido propiophenone and derivative thereof can be obtained in mild conditions, conventional expensive azoic compound materials are not used, the cost is lowered to a large extent, the operation requirement is also lowered, and alpha-amido propiophenone and derivative thereof have good application prospect in industry.
