Check Digit Verification of cas no

The CAS Registry Mumber 180961-72-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,9,6 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 180961-72:
(8*1)+(7*8)+(6*0)+(5*9)+(4*6)+(3*1)+(2*7)+(1*2)=152
152 % 10 = 2
So 180961-72-2 is a valid CAS Registry Number.

One-pot sequential asymmetric hydrogenation of β-aryl-β-aryloxy acroleins

Liu, Yufeng,Chen, Jianzhong,Zhang, Zhenfeng,Qin, Jian,Zhao, Min,Zhang, Wanbin

, p. 7099 - 7102 (2016/07/30)

A one-pot sequential asymmetric hydrogenation of β-aryl-β-aryloxy acroleins has been realized for the preparation of chiral 3-aryl-3-aryloxy alcohols with excellent yields and good enantioselectivities. This methodology can be employed in new synthetic routes for the synthesis of fluoxetine, atomoxetine, and related analogues.

A stereospecific ruthenium-catalyzed allylic alkylation

Trost, Barry M.,Fraisse, Pierre L.,Ball, Zachary T.

, p. 1059 - 1061 (2007/10/03)

Good regioselectivity and chirality transfer for aryl-substituted allyl units is achieved in allylic alkylations with a wide range of nucleophiles by using the highly active ruthenium catalyst 1. This method provides a route to antidepressants such as (-)-fluoxetine from (S)-ephedrine (see scheme; Cp* = η5-C5Me5, TBAT = tetrabutylammonium triphenyldifluorosilicate).
