4-[[(Phenylsulfonyl)oxy]imino]-2,5-cyclohexadien-1-one is a complex organic compound with the molecular formula C13H9NO3S. It is characterized by a cyclohexadienone core, which is a six-membered ring with alternating double and single bonds, and a phenylsulfonyl group attached to the nitrogen atom in the imino position. 4-[[(Phenylsulfonyl)oxy]imino]-2,5-cyclohexadien-1-one is a derivative of benzene, with a sulfonyl group (-SO2-) connecting the phenyl ring to the nitrogen atom. The molecule also contains a carbonyl group, which is a carbon-oxygen double bond, and a hydroxyl group (-OH) attached to the phenyl ring. This chemical is known for its potential applications in the synthesis of various pharmaceuticals and agrochemicals, as well as its role as an intermediate in organic chemistry. Due to its reactivity and functional groups, it is often used in the formation of new compounds through substitution and addition reactions.

Check Digit Verification of cas no

The CAS Registry Mumber 1831-69-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,3 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1831-69:
(6*1)+(5*8)+(4*3)+(3*1)+(2*6)+(1*9)=82
82 % 10 = 2
So 1831-69-2 is a valid CAS Registry Number.

Avdeenko, A. P.,Glinyanaya, N. M.,Pirozhenko, V. V.

, p. 1066 - 1070 (2007/10/03)

Addition of cyclopentadiene to unsubstituted O-acyl-1,4-benzoquinone monooximes or their 2- or 3-methyl derivatives across the double bond of the quinone ring yielded the only endo-Z isomer, in spite of the possibility for isomerization around the C=N bon

Chlorination and Bromination of 4-Arylsulfonyloxyimino-2,5-Cyclohexadien-1-Ones and 1,4-Di(arylsulfonyloxyimino)-2,5-Cyclohexadienes
