The chemical "3,9-Bis-(2,6-dibrom-4-nitro-phenoxy)-2,4,8,10-tetraoxa-3,9-diphospha-spiro<5,5>undecan-3,9-disulfid" is a complex, organophosphorus compound with a unique structure. It features a spiro[5,5]undecane core, which is a cyclic structure consisting of five carbon atoms. Attached to this core are two disulfide bridges, which are sulfur-sulfur bonds, and two 2,6-dibrom-4-nitro-phenoxy groups. These groups are derived from phenol, a benzene ring with a hydroxyl group, and are substituted with bromine atoms at the 2 and 6 positions and a nitro group at the 4 position. The compound's structure and properties make it potentially useful in various applications, such as in the synthesis of other complex molecules or as a component in specialized materials.
The CAS Registry Mumber 6263-79-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,6 and 3 respectively; the second part has 2 digits, 7 and 9 respectively. Calculate Digit Verification of CAS Registry Number 6263-79: (6*6)+(5*2)+(4*6)+(3*3)+(2*7)+(1*9)=102 102 % 10 = 2 So 6263-79-2 is a valid CAS Registry Number.
