Check Digit Verification of cas no

The CAS Registry Mumber 1627500-27-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,7,5,0 and 0 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1627500-27:
(9*1)+(8*6)+(7*2)+(6*7)+(5*5)+(4*0)+(3*0)+(2*2)+(1*7)=149
149 % 10 = 9
So 1627500-27-9 is a valid CAS Registry Number.

Ruthenium-catalyzed hydroaroylation of styrenes in water through directed C-H bond activation

, p. 1562 - 1566 (2014/06/24)

Selective C-H bond-functionalization reactions of arenes offer the potential for a more benign synthesis of fine chemicals and organic building blocks for the life science industries. In this respect, direct carbonylative coupling reactions of (hetero)arenes allow for the straightforward synthesis of (hetero)aromatic ketones and related derivatives. Herein, we present an efficient ruthenium(II)-catalyzed carbonylative hydroarylation of alkenes through directed C-H functionalization. More specifically, the carbonylative hydroarylation of styrenes with 2-aryl- (heteroaryl)pyridines and related derivatives proceeds selectively and with 100 % atom efficiency in water as the solvent. Three-Component Hydroaroylation: Hydroaroylation through C-H activation of (hetero)arenes bearing ortho-directing groups (DGs) proceeds in the presence of a ruthenium catalyst, carbon monoxide, and styrenes. The shown coupling process provides selective and atom-economic access to (hetero)- aromatic ketones.
