Check Digit Verification of cas no

The CAS Registry Mumber 116941-04-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,9,4 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 116941-04:
(8*1)+(7*1)+(6*6)+(5*9)+(4*4)+(3*1)+(2*0)+(1*4)=119
119 % 10 = 9
So 116941-04-9 is a valid CAS Registry Number.

Trans-Selective and Switchable Arene Hydrogenation of Phenol Derivatives

Bergander, Klaus,Glorius, Frank,Heusler, Arne,Wollenburg, Marco

, p. 11365 - 11370 (2020/11/24)

A trans-selective arene hydrogenation of abundant phenol derivatives catalyzed by a commercially available heterogeneous palladium catalyst is reported. The described method tolerates a variety of functional groups and provides access to a broad scope of trans-configurated cyclohexanols as potential building blocks for life sciences and beyond in a one-step procedure. The transformation is strategically important because arene hydrogenation preferentially delivers the opposite cis-isomers. The diastereoselectivity of the phenol hydrogenation can be switched to the cis-isomers by employing rhodium-based catalysts. Moreover, a protocol for the chemoselective hydrogenation of phenols to cyclohexanones was developed.
