"2,2,4,4-tetramethyl-8,8,10,10-tetraphenylspiro[5.5]pentasila-1,5-diaza-3,7,9,11-tetraoxane" is a complex organic-inorganic hybrid compound, characterized by its unique spiro structure. The molecule features a pentasila (Si5) ring, which is a cyclic structure consisting of five silicon atoms. Attached to this ring are two nitrogen atoms, forming a diaza group, and four oxygen atoms, creating a tetraoxane structure. The compound is further adorned with two methyl groups (CH3) and four phenyl groups (C6H5), which are attached to specific carbon atoms within the molecule. This intricate arrangement of atoms results in a highly symmetrical and stable molecule, with potential applications in materials science and as a precursor in the synthesis of other complex organosilicon compounds.
The CAS Registry Mumber 70608-78-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,6,0 and 8 respectively; the second part has 2 digits, 7 and 8 respectively. Calculate Digit Verification of CAS Registry Number 70608-78: (7*7)+(6*0)+(5*6)+(4*0)+(3*8)+(2*7)+(1*8)=125 125 % 10 = 5 So 70608-78-5 is a valid CAS Registry Number.
