1.1.7-Trichlor-3.3.5.5.7.7-hexamethyl-1-phenyl-tetrasiloxan is a complex organosilicon compound with the chemical formula C12H21Cl3O2Si4. It consists of a tetrasiloxane backbone, which is a cyclic structure containing four silicon atoms and four oxygen atoms, with three chlorine atoms attached to one of the silicon atoms and a phenyl group (C6H5) attached to another silicon atom. The remaining two silicon atoms are connected to three methyl groups (CH3) each. 1.1.7-Trichlor-3.3.5.5.7.7-hexamethyl-1-phenyl-tetrasiloxan is characterized by its high thermal stability, low toxicity, and excellent electrical insulating properties, making it a potential candidate for various applications in the fields of materials science, electronics, and chemical engineering.
The CAS Registry Mumber 6417-74-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,1 and 7 respectively; the second part has 2 digits, 7 and 4 respectively. Calculate Digit Verification of CAS Registry Number 6417-74: (6*6)+(5*4)+(4*1)+(3*7)+(2*7)+(1*4)=99 99 % 10 = 9 So 6417-74-9 is a valid CAS Registry Number.
