Check Digit Verification of cas no

The CAS Registry Mumber 83305-63-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,3,0 and 5 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 83305-63:
(7*8)+(6*3)+(5*3)+(4*0)+(3*5)+(2*6)+(1*3)=119
119 % 10 = 9
So 83305-63-9 is a valid CAS Registry Number.

α-Arylation of Carbonyl Compounds through Oxidative C?C Bond Activation

Li, Jing,Bauer, Adriano,Di Mauro, Giovanni,Maulide, Nuno

, p. 9816 - 9819 (2019)

A synthetically useful approach for the direct α-arylation of carbonyl compounds through a novel oxidative C?C bond activation is reported. This mechanistically unusual process relies on a 1,2-aryl shift and results in all-carbon quaternary centers. The transformation displays broad functional-group tolerance and can in principle also be applied as an asymmetric variant.
