α,ω-Bis-(chlormethyl)-decamethylpentasiloxane is a cyclic siloxane compound with the chemical formula C10H24Cl2O5Si5. It consists of a five-membered siloxane ring with decamethyl substituents (10 methyl groups) and two chloromethyl groups attached to the terminal silicon atoms. α.ω-Bis--dekamethylpentasiloxan is primarily used as a cross-linking agent in the production of silicone rubber and resins, as well as a coupling agent in various applications, including adhesives, sealants, and coatings. Due to its reactive chloromethyl groups, it can easily form covalent bonds with other molecules, enhancing the overall performance and durability of the materials in which it is incorporated.

18138-53-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 18138-53-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,1,3 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.Calculate Digit Verification of CAS Registry Number 18138-53:
(7*1)+(6*8)+(5*1)+(4*3)+(3*8)+(2*5)+(1*3)=109
109 % 10 = 9
So 18138-53-9 is a valid CAS Registry Number.
