Check Digit Verification of cas no

The CAS Registry Mumber 28586-49-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,5,8 and 6 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 28586-49:
(7*2)+(6*8)+(5*5)+(4*8)+(3*6)+(2*4)+(1*9)=154
154 % 10 = 4
So 28586-49-4 is a valid CAS Registry Number.

Asymmetric Transfer Hydrogenation of o-Hydroxyphenyl Ketones: Utilizing Directing Effects That Optimize the Asymmetric Synthesis of Challenging Alcohols

Clarkson, Guy J.,Wills, Martin,Zheng, Ye

, (2020/05/05)

A systematic range of o-hydroxyphenyl ketones were reduced under asymmetric transfer hydrogenation conditions using the C3-tethered catalyst 2. Two directing effects, i.e., an o-hydroxyphenyl coupled to a bulky aromatic on the opposite side of the ketone substrate, combine in a matched manner to deliver reduction products with very high enantiomeric excess.
