Check Digit Verification of cas no

The CAS Registry Mumber 65943-18-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,9,4 and 3 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 65943-18:
(7*6)+(6*5)+(5*9)+(4*4)+(3*3)+(2*1)+(1*8)=152
152 % 10 = 2
So 65943-18-2 is a valid CAS Registry Number.

Aerobic Oxidative Dehydrogenation of Ketones to 1,4-Enediones

Zhao, Bao-Yin,Zhang, Xing-Long,Guo, Rui-Li,Wang, Meng-Yue,Gao, Ya-Ru,Wang, Yong-Qiang

supporting information, p. 1216 - 1221 (2021/02/20)

An efficient and unprecedented strategy for the synthesis of 1,4-enediones from saturated ketones has been developed via palladium-catalyzed oxidative dehydrogenation. The protocol employs molecular oxygen as the sole oxidant and represents an atom- and step-economic process. The approach showed broad substrate scope, good functional group tolerance, and complete E-stereoselectivity. The reaction mechanism has been investigated through deuterium-labeling experiments and intermediate experiments.
