Check Digit Verification of cas no

The CAS Registry Mumber 55164-28-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,1,6 and 4 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 55164-28:
(7*5)+(6*5)+(5*1)+(4*6)+(3*4)+(2*2)+(1*8)=118
118 % 10 = 8
So 55164-28-8 is a valid CAS Registry Number.

Photodriven Dehydrogenative Homocoupling of Benzylic C-H Bonds Forming Strained C-C Bonds

supporting information, p. 2067 - 2070 (2021/10/14)

A photoinduced dehydrogenative homocoupling reaction of alkylarenes is reported. Gaseous hydrogen is evolved as the sole byproduct and neither oxidants nor hydrogen acceptors are required. The present reaction offers an environmentally benign and atom-economical means for forming sterically strained C-C single bonds. It also gives a remarkable example of photodriven reactions overcoming a considerable rise in energy.
