Check Digit Verification of cas no

The CAS Registry Mumber 71969-28-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,9,6 and 9 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 71969-28:
(7*7)+(6*1)+(5*9)+(4*6)+(3*9)+(2*2)+(1*8)=163
163 % 10 = 3
So 71969-28-3 is a valid CAS Registry Number.

Photocatalytic C-H Amination of Aromatics Overcoming Redox Potential Limitations

Ikarashi, Gun,Kano, Naokazu,Morofuji, Tatsuya

supporting information, p. 2822 - 2827 (2020/04/16)

We report the photocatalytic C-H amination of aromatics overcoming redox potential limitations. Radical cations of aromatic compounds are generated photocatalytically using Ru(phen)3(PF6)2, which has a reduction potential at a high oxidation state (Ered(RuIII/RuII) = +1.37 V vs SCE) lower than the oxidation potentials of aromatic substrates (Eox = +1.65 to +2.27 V vs SCE). The radical cations are trapped with pyridine to give N-arylpyridinium ions, which were converted to aromatic amines.
