Tripentyl-phenoxy-silane, also known as 1,1,1,3,3,3-hexamethyl-3-(4-phenoxyphenyl)disiloxane, is an organosilicon compound with the chemical formula C21H30OSi2. It is a colorless liquid with a molecular weight of 354.63 g/mol. tripentyl-phenoxy-silane is characterized by its unique structure, which includes two pentyl groups, a phenoxy group, and two silicon atoms connected by an oxygen bridge. Tripentyl-phenoxy-silane is primarily used as a coupling agent in the production of silicone rubber, where it enhances the adhesion between the rubber and various substrates such as glass, metal, and plastic. It is also employed as a stabilizer in the silicone industry and as a crosslinking agent in the synthesis of silicone-based materials. Due to its reactive nature, it is essential to handle tripentyl-phenoxy-silane with care, following proper safety protocols.

Check Digit Verification of cas no

The CAS Registry Mumber 18751-28-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,7,5 and 1 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 18751-28:
(7*1)+(6*8)+(5*7)+(4*5)+(3*1)+(2*2)+(1*8)=125
125 % 10 = 5
So 18751-28-5 is a valid CAS Registry Number.
