18304-82-0 Usage
General Description
1,3,5,7,9,11-hexamethyl-1,3,5,7,9,11-hexavinylcyclohexasiloxane, also known as HMVCHS, is a chemical compound belonging to the family of silicones. It is a cyclic compound with six silicon atoms and twelve methyl and vinyl groups, making it highly hydrophobic and stable. HMVCHS is commonly used in the formulation of sealants, adhesives, and coatings due to its excellent water repellent and chemical resistant properties. It also finds applications in the electronics industry as a protective coating for electronic components. Moreover, it is used in the production of silicone rubber and elastomers. Due to its unique structure and properties, HMVCHS is considered a versatile and effective silicone compound.
Check Digit Verification of cas no
The CAS Registry Mumber 18304-82-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,3,0 and 4 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 18304-82:
(7*1)+(6*8)+(5*3)+(4*0)+(3*4)+(2*8)+(1*2)=100
100 % 10 = 0
So 18304-82-0 is a valid CAS Registry Number.

Reaction of organylchlorosilanes with dimethyl sulfoxide in the presence of octamethyltrisiloxane
Basenko,Gebel',Boyarkina,Voronkov
, p. 882 - 884 (2007/10/03)
Dichloro(methyl)(vinyl)silane reacts with DMSO in the presence of octamethyltrisiloxane to form cyclooligomethyl(vinyl)siloxanes(MeViSiO) n (n = 3-6). The reaction involves disproportionation of octamethyltrisiloxane into hexamethyldisiloxane and decamethyltetrasiloxane. Along with the latter two products, insertion products of methyl vinyl silanone into both permethyloligosiloxanes were identified. Alkyltrichlorosilanes RSiCl3 (R = Me, Et) react with DMSO in the presence of octamethyltrisiloxane to form cyclic oligoalkyltrichlorosiloxanes (RClSiO) m (m = 3-6).
