33934-64-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 33934-64-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,9,3 and 4 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 33934-64:
(7*3)+(6*3)+(5*9)+(4*3)+(3*4)+(2*6)+(1*4)=124
124 % 10 = 4
So 33934-64-4 is a valid CAS Registry Number.

Tert -Butoxide-Mediated Arylation of 1-Acetylindolin-3-ones with Diaryliodonium Salts

Zhang, Yanxia,Han, Jianwei,Liu, Zhen-Jiang

, p. 2593 - 2597 (2015)

A procedure for the 2-arylations of indolinone derivatives with diaryliodonium salts mediated by potassium tert-butoxide is developed. Various monoarylated indolinone derivatives are readily obtained in 24-70% yield via this method. The alkylation of monoarylated indolinone derivatives with allyl bromide or benzyl bromide affords the corresponding 2,3-disubstituted products in 60% and 70% yield, respectively.
