Check Digit Verification of cas no

The CAS Registry Mumber 248602-19-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,8,6,0 and 2 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 248602-19:
(8*2)+(7*4)+(6*8)+(5*6)+(4*0)+(3*2)+(2*1)+(1*9)=139
139 % 10 = 9
So 248602-19-9 is a valid CAS Registry Number.

Pd-Catalyzed Dearomatization of Indole Derivatives via Intermolecular Heck Reactions?

Yang, Ping,Xu, Ren-Qi,Zheng, Chao,You, Shu-Li

supporting information, p. 235 - 241 (2020/01/28)

Pd-catalyzed intermolecular dearomative Heck reaction of indoles with aryl iodides is described. The challenges on both reactivity and regioselectivity are addressed by the judicious regulation of the geometric and electronic properties of the substrates. An array of indoline derivatives bearing C2-quaternary center is obtained in good to excellent yields (up to 93%) with exclusive regioselectivity under operationally simple conditions. The mechanistic proposal is supported by detailed DFT calculations.

Synthesis of novel indole derivatives: Variations in the Bartoli reaction

Dobbs, Adrian P.,Voyle, Martyn,Whittall, Neil

, p. 1594 - 1596 (2007/10/03)

The synthesis of a range of novel substituted indoles and tricyclic indole derivatives is described using an extension of the Bartoli methodology.
