It consists of a spiro framework with seven oxygen atoms and seven silicon atoms, forming a heptacyclic structure. The compound is characterized by the presence of ten methyl groups attached to the silicon atoms, which contribute to its stability and reactivity. This specific arrangement of atoms and functional groups gives the compound distinct physical and chemical properties, making it a subject of interest in the field of organosilicon chemistry.
The CAS Registry Mumber 17995-45-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,9,9 and 5 respectively; the second part has 2 digits, 4 and 5 respectively. Calculate Digit Verification of CAS Registry Number 17995-45: (7*1)+(6*7)+(5*9)+(4*9)+(3*5)+(2*4)+(1*5)=158 158 % 10 = 8 So 17995-45-8 is a valid CAS Registry Number.
