Tris-(2-cyclohexyl-ethyl)-dodecyl-silane is a complex organic compound with the molecular formula C39H76Si. It is a type of silane, which is a derivative of silicon hydride where one or more hydrogen atoms are replaced by alkyl or aryl groups. This particular silane is characterized by its three cyclohexyl-ethyl chains and a dodecyl chain attached to a central silicon atom. It is known for its unique properties, such as its ability to act as a coupling agent in the formation of composite materials, enhancing the adhesion between inorganic and organic components. Due to its hydrophobic nature and thermal stability, it finds applications in various industries, including coatings, adhesives, and sealants, where it can improve the performance and durability of materials.
The CAS Registry Mumber 18817-67-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,8,1 and 7 respectively; the second part has 2 digits, 6 and 7 respectively. Calculate Digit Verification of CAS Registry Number 18817-67: (7*1)+(6*8)+(5*8)+(4*1)+(3*7)+(2*6)+(1*7)=139 139 % 10 = 9 So 18817-67-9 is a valid CAS Registry Number.
