79726-13-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 79726-13-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,7,2 and 6 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 79726-13:
(7*7)+(6*9)+(5*7)+(4*2)+(3*6)+(2*1)+(1*3)=169
169 % 10 = 9
So 79726-13-9 is a valid CAS Registry Number.

Reactivity of 2,3-Dihydrobenzothiophene-3-one-1,1-dioxide
Ried, Walter,Oremek, Gerhard
, p. 619 - 622 (2007/10/02)
The benzothiophene-1,1-dioxides 2a-d and 3a-c react on warming to 2,3-dihydrobenzothiophene-3-one-1,1-dioxide (1).Compound 1 react with Amines, Hydrazines and Triphenylphosphoranes to give the condensationproducts 4, 7, and 9.With HN3 the Lactam 5 is formed.
