310435-53-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 310435-53-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,0,4,3 and 5 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 310435-53:
(8*3)+(7*1)+(6*0)+(5*4)+(4*3)+(3*5)+(2*5)+(1*3)=91
91 % 10 = 1
So 310435-53-1 is a valid CAS Registry Number.

Conversion of 3-nitroanilines into tricyclic systems: 1H-1-alkyl-8-X-2,2-dioxoisothiazolo[5,4,3-d,e]quinolines
Wróbel, Zbigniew
, p. 7899 - 7907 (2007/10/03)
The route leading to the tricyclic 2,2-dioxoisothiazolo[5,4,3-d,e]quinolines from 3-nitroanilines has been described. The scope and limitation factors as well as some mechanistic features are discussed.
