Check Digit Verification of cas no
The CAS Registry Mumber 39203-20-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,2,0 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 39203-20:
(7*3)+(6*9)+(5*2)+(4*0)+(3*3)+(2*2)+(1*0)=98
98 % 10 = 8
So 39203-20-8 is a valid CAS Registry Number.

Oxidative Route to Indoles via Intramolecular Amino-Hydroxylation of o-Allenyl Anilines
Lauta, Nicholas R.,Williams, Ryan E.,Smith, David T.,Kumirov, Vlad K.,Njardarson, Jon T.
, p. 10713 - 10723 (2021/07/31)
A new intramolecular oxidative amino-hydroxylation of o-allenyl anilines is reported. Treatment of carbamate-protected anilines with lead(IV) carboxylates in dichloromethane at room temperature results in facile tandem C-N (allene cyclization) and C-O bon

Suarez-Castillo, Oscar R.,Melendez-Rodriguez, Myriam,Morales-Garcia, Ana L.,Cano-Escudero, Indira C.,Contreras-Martinez, Yaneth M.A.,Morales-Rios, Martha S.,Joseph-Nathan, Pedro
experimental part, p. 1463 - 1476 (2009/12/24)
An improved synthesis of N1-carbomethoxylated indolylindolines 2 from 5-substituted indoles 1, by replacing the previously employed strong acids or toxic metals with t-BuNH2/MeOCOCl in CH2Cl2/H2O, is described.
