Ethylthio-dimethyl-chlor-silan, also known as chloro(dimethyl)(ethylthio)silane or (C2H5S)(Me2SiCl), is an organosilicon compound characterized by the presence of a silicon atom bonded to a chlorine atom, two methyl groups, and an ethylthio group. This colorless liquid is an important intermediate in the synthesis of various organosilicon compounds and is used in the production of silicones, silane coupling agents, and other specialty chemicals. It is also employed as a reagent in organic synthesis and as a precursor for the formation of silyl ethers. Ethylthio-dimethyl-chlor-silan is sensitive to moisture and air, and it is typically handled under an inert atmosphere to prevent unwanted side reactions.

Check Digit Verification of cas no

The CAS Registry Mumber 3553-83-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,5,5 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3553-83:
(6*3)+(5*5)+(4*5)+(3*3)+(2*8)+(1*3)=91
91 % 10 = 1
So 3553-83-1 is a valid CAS Registry Number.
