Disilicic acid hexaphenyl ester, also known as hexaphenyl disilicate, is a chemical compound with the formula (C6H5)3Si-O-Si(C6H5)3. It is a colorless, crystalline solid that is derived from disilicic acid, which is a silicic acid with two silicon atoms. disilicic acid hexaphenyl ester is characterized by its symmetrical structure, where two phenyl groups are attached to each silicon atom, and an oxygen atom bridges the two silicon centers. It is an organosilicon compound, which means it contains silicon atoms bonded to carbon atoms. Disilicic acid hexaphenyl ester is used in the synthesis of various organosilicon compounds and as a precursor in the production of silicones. It is also of interest in materials science due to its potential applications in the development of new materials with unique properties.
The CAS Registry Mumber 3561-94-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,5,6 and 1 respectively; the second part has 2 digits, 9 and 4 respectively. Calculate Digit Verification of CAS Registry Number 3561-94: (6*3)+(5*5)+(4*6)+(3*1)+(2*9)+(1*4)=92 92 % 10 = 2 So 3561-94-2 is a valid CAS Registry Number.
