α,ω-Dichlor-eicosamethyl-decasiloxan is a complex organosilicon compound characterized by a decasiloxane backbone, which consists of ten silicon atoms connected by oxygen bridges. The molecule features two terminal chloro groups (α and ω) and twenty methyl groups attached to the silicon atoms. This unique structure endows the compound with specific properties, such as thermal stability and low reactivity, making it useful in various applications, including as a precursor in the synthesis of silicone polymers and as a component in specialty coatings and adhesives. Its high molecular weight and siloxane linkages contribute to its resistance to degradation and its ability to form robust materials with unique physical properties.

18772-68-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 18772-68-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,7,7 and 2 respectively; the second part has 2 digits, 6 and 8 respectively.Calculate Digit Verification of CAS Registry Number 18772-68:
(7*1)+(6*8)+(5*7)+(4*7)+(3*2)+(2*6)+(1*8)=144
144 % 10 = 4
So 18772-68-4 is a valid CAS Registry Number.
