Check Digit Verification of cas no

The CAS Registry Mumber 1416897-52-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,6,8,9 and 7 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1416897-52:
(9*1)+(8*4)+(7*1)+(6*6)+(5*8)+(4*9)+(3*7)+(2*5)+(1*2)=193
193 % 10 = 3
So 1416897-52-3 is a valid CAS Registry Number.

One-Pot Tandem ortho-Naphthoquinone-Catalyzed Aerobic Nitrosation of N-Alkylanilines and Rh(III)-Catalyzed C-H Functionalization Sequence to Indole and Aniline Derivatives

Si, Tengda,Kim, Hun Young,Oh, Kyungsoo

, p. 1152 - 1163 (2021/01/14)

The nitroso group served as a traceless directing group for the C-H functionalization of N-alkylanilines, ultimately removed after functioning either as an internal oxidant or under subsequent reducing conditions. The unique ability of o-NQ catalysts to aerobically oxidize the N-alkylanilines without using solvents and stoichiometric amounts of oxidants has rendered the new opportunity to develop the telescoped catalyst systems without a need for directly handling the hazardous N-nitroso compounds.
