126556-53-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126556-53-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,5,5 and 6 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 126556-53:
(8*1)+(7*2)+(6*6)+(5*5)+(4*5)+(3*6)+(2*5)+(1*3)=134
134 % 10 = 4
So 126556-53-4 is a valid CAS Registry Number.

Synthesis of 4-(O-Arylsulfonyl)quinoline-5,8-quinones
Fernandez, Mario,Lin, Tai-Shun,Sartorelli, Alan C.
, p. 2647 - 2658 (2007/10/02)
Synthesis of a series of 4-(O-arylsulfonyl)quinoline-5,8-quinones 9 is described.This was accomplished by the direct sulfonylation of the readily available quinolinone 7 by a variety of arylsulfonyl chlorides followed by oxidation of the resulting 5,8-dim
