Tetrasiloxane, 1,7-diethoxy-1,3,5,7-tetramethyl-1,3,5,7-tetraphenyl- is a complex organic-inorganic hybrid compound, characterized by its unique structure consisting of a cyclic siloxane backbone with alternating silicon and oxygen atoms. The compound is further modified by the presence of four methyl groups and four phenyl groups attached to the silicon atoms, as well as two ethoxy groups at the 1 and 7 positions. This specific arrangement of functional groups endows the compound with unique properties, such as enhanced thermal stability and low surface tension, making it potentially useful in various applications, including as a component in silicone-based materials, surfactants, and lubricants. The compound's molecular formula is C28H44O4Si4, reflecting its composition of carbon, hydrogen, oxygen, and silicon atoms.

3909-67-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 3909-67-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,0 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.Calculate Digit Verification of CAS Registry Number 3909-67:
(6*3)+(5*9)+(4*0)+(3*9)+(2*6)+(1*7)=109
109 % 10 = 9
So 3909-67-9 is a valid CAS Registry Number.
