Check Digit Verification of cas no

The CAS Registry Mumber 14198-45-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,1,9 and 8 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 14198-45:
(7*1)+(6*4)+(5*1)+(4*9)+(3*8)+(2*4)+(1*5)=109
109 % 10 = 9
So 14198-45-9 is a valid CAS Registry Number.

Visible-Light-Driven Aryl Migration and Cyclization of α-Azido Amides

Liang, Siyu,Wei, Kaijie,Lin, Yajun,Liu, Tuming,Wei, Dian,Han, Bing,Yu, Wei

supporting information, p. 4527 - 4531 (2021/06/28)

This paper reports two new visible-light-promoted radical reactions of α-azido amides. By catalysis of [Ir(ppy)2(dtbbpy)]PF6 with i-Pr2NEt as the reducing agent, N-aryl α-azido tertiary amides were first converted to the corresponding aminyl radicals through reduction of the azido group; the aminyl radicals then underwent N-to-N aryl migration to give α-anilinyl-functionalized amides. α-Azido secondary amides, on the other hand, reacted with the solvent ethanol and i-Pr2NEt to afford the imidazolinone products.
