The chemical "3,9-Bis-(2,6-dichlor-4-nitro-phenoxy)-2,4,8,10-tetraoxa-3,9-diphospha-spiro<5,5>undecan-3,9-disulfid" is a complex organic 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 phenoxy groups. Each phenoxy group is substituted with a 2,6-dichlor-4-nitro group, which means there are two chlorine atoms at the 2nd and 6th positions and a nitro group at the 4th position of the benzene ring. The compound is characterized by its potential applications in various fields, such as pharmaceuticals or materials science, due to its specific structural features and reactivity.
The CAS Registry Mumber 5305-90-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,0 and 5 respectively; the second part has 2 digits, 9 and 0 respectively. Calculate Digit Verification of CAS Registry Number 5305-90: (6*5)+(5*3)+(4*0)+(3*5)+(2*9)+(1*0)=78 78 % 10 = 8 So 5305-90-8 is a valid CAS Registry Number.
