3,9-Bis-(4-nitrophenyloxy)-2,4,8,10-tetraoxa-3,9-diphospha-spiro<5,5>undecan-3,9-disulfid is a complex organic compound characterized by its unique structure. It features a spiro[5,5]undecane core, which is a cyclic structure with five carbon atoms in each of the two rings that are connected at a single point. The compound is further defined by the presence of two disulfide bridges (-S-S-) at the 3 and 9 positions, which contribute to its stability and reactivity. Additionally, it has two 4-nitrophenoxy groups attached to the phosphorus atoms, which are part of the diphosphaspiro framework. These nitrophenoxy groups are known for their strong electron-withdrawing properties and can significantly influence the compound's chemical behavior. This molecule is of interest in the field of organophosphorus chemistry, potentially for its applications in materials science or as a precursor in the synthesis of other complex molecules.
The CAS Registry Mumber 5305-93-1 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 3 respectively. Calculate Digit Verification of CAS Registry Number 5305-93: (6*5)+(5*3)+(4*0)+(3*5)+(2*9)+(1*3)=81 81 % 10 = 1 So 5305-93-1 is a valid CAS Registry Number.
