93533-99-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 93533-99-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,5,3 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 93533-99:
(7*9)+(6*3)+(5*5)+(4*3)+(3*3)+(2*9)+(1*9)=154
154 % 10 = 4
So 93533-99-4 is a valid CAS Registry Number.

Direct α-Chalcogenation of Aliphatic Carboxylic Acid Equivalents
Gupta, Aniket,Rahaman, Ajijur,Bhadra, Sukalyan
, p. 6164 - 6168 (2019/08/20)
A novel approach to α-chalcogenation of aliphatic carboxylic acids has been developed by means of transforming them as the corresponding benzazoles. The catalyst system, consisting of CuI, DMSO, and a base, operates through a unique mechanism t
