"3,9-Bis-(4-nitrophenyloxy)-2,4,8,10-tetraoxa-3,9-diphospha-spiro<5,5>undecan-3,9-dioxid" is a complex organic compound characterized by its unique structure. It features a spiro[5,5]undecane core, which is a cyclic structure with two carbon atoms shared between two rings. The compound is further defined by the presence of two phosphorus atoms, which, along with oxygen, form the diphosphaspiro framework. Each phosphorus atom is connected to a 4-nitrophenoxy group, which contributes to the compound's reactivity and properties. The tetraoxa component refers to the four oxygen atoms that are part of the ring structure. 3,9-Bis-(4-nitrophenyloxy)-2,4,8,10-tetraoxa-3,9-diphospha-spiro<5,5>undecan-3,9-dioxid is of interest in the field of organophosphorus chemistry due to its potential applications in areas such as catalysis and material science.
The CAS Registry Mumber 5305-94-2 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 4 respectively. Calculate Digit Verification of CAS Registry Number 5305-94: (6*5)+(5*3)+(4*0)+(3*5)+(2*9)+(1*4)=82 82 % 10 = 2 So 5305-94-2 is a valid CAS Registry Number.
