Check Digit Verification of cas no

The CAS Registry Mumber 1599438-40-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,9,9,4,3 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1599438-40:
(9*1)+(8*5)+(7*9)+(6*9)+(5*4)+(4*3)+(3*8)+(2*4)+(1*0)=230
230 % 10 = 0
So 1599438-40-0 is a valid CAS Registry Number.

Dual visible light photoredox and gold-catalyzed arylative ring expansion

Shu, Xing-Zhong,Zhang, Miao,He, Ying,Frei, Heinz,Toste, F. Dean

, p. 5844 - 5847 (2014/05/20)

A combination of visible light photocatalysis and gold catalysis is applied to a ring expansion-oxidative arylation reaction. The reaction provides an entry into functionalized cyclic ketones from the coupling reaction of alkenyl and allenyl cycloalkanols with aryl diazonium salts. A mechanism involving generation of an electrophilic gold(III)-aryl intermediate is proposed on the basis of mechanistic studies, including time-resolved FT-IR spectroscopy.
