908003-67-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 908003-67-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,8,0,0 and 3 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 908003-67:
(8*9)+(7*0)+(6*8)+(5*0)+(4*0)+(3*3)+(2*6)+(1*7)=148
148 % 10 = 8
So 908003-67-8 is a valid CAS Registry Number.

Pd-tBuONO Cocatalyzed Aerobic Indole Synthesis

Ning, Xiao-Shan,Liang, Xin,Hu, Kang-Fei,Yao, Chuan-Zhi,Qu, Jian-Ping,Kang, Yan-Biao

, p. 1590 - 1594 (2018)

A Pd-tBuONO co-catalyzed scalable and practical synthesis of indoles with molecular oxygen as terminal oxidant is developed. Either terminal or internal 2-vinylanilines could be smoothly converted to desired indoles under one general condition. This method has been evaluated in the large scale synthesis of indomethacin and a potential anti-breast cancer drug candidate 1. (Figure presented.).

Total synthesis of the alkaloid (±)-aspidophytine based on carbonyl ylide cycloaddition chemistry

Mejia-Oneto, Jose M.,Padwa, Albert

experimental part, p. 285 - 302 (2009/02/07)

The RhII-catalyzed cycloaddition cascade of an indolyl-substituted α-diazo imide was used for the total synthesis of the complex pentacyclic alkaloid (±)-aspidophytine. Treatment of the resulting dipolar cycloadduct with BF3·OEt
