Quinoxaline, 2-phenyl-, 1,4-dioxide, also known as 2-phenylquinoxaline 1,4-dioxide, is a chemical compound with the molecular formula C13H9NO2. It is a derivative of quinoxaline, a fused bicyclic compound consisting of a benzene ring fused to a diazine ring. The 2-phenyl substitution refers to a phenyl group (C6H5) attached to the second carbon of the quinoxaline ring, while the 1,4-dioxide indicates the presence of two oxygen atoms bonded to the first and fourth carbons of the quinoxaline ring, forming a dioxo group. Quinoxaline, 2-phenyl-, 1,4-dioxide is an important intermediate in the synthesis of various pharmaceuticals and agrochemicals, and it exhibits a range of biological activities, including anti-inflammatory, analgesic, and antipyretic properties.

Check Digit Verification of cas no

The CAS Registry Mumber 5023-53-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,2 and 3 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5023-53:
(6*5)+(5*0)+(4*2)+(3*3)+(2*5)+(1*3)=60
60 % 10 = 0
So 5023-53-0 is a valid CAS Registry Number.

Synthesis of 2-substituted-quinoxaline-1,4 dioxides

Li, Jiaming,Ji, Min,Hua, Weiyi,Hu, Hongwen

, p. 1230 - 1231 (2007/10/03)

Six new 2-substituted-quinoxaline-1,4-dioxides(3) have been prepared by reacting benzofuroxan (BFO)(1) with alkenes(2). The reaction is proposed as a free radical mechanism.
