General Description
Bis(trimethylsilyl)sebacate, also known as decanedioic acid bis(trimethylsilyl) ester, is a chemical compound with the molecular formula C18H38O4Si2. The compound belongs to the organic silicons category and is derived from sebacic acid and trimethylsilane. It's a colorless liquid and is widely used in industrial applications such as the production of adhesives, sealants, and lubricants. It is also a processing aid in the manufacture of rubber products. Despite its industrial significance, there is a lack of data about its environmental and human health impacts.
Check Digit Verification of cas no
The CAS Registry Mumber 18408-42-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,4,0 and 8 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 18408-42:
(7*1)+(6*8)+(5*4)+(4*0)+(3*8)+(2*4)+(1*2)=109
109 % 10 = 9
So 18408-42-9 is a valid CAS Registry Number.

Dealkylation of esters via treatment with N-(trimethylsilyl) diethylamine and methyl iodide
Yamamoto, Yasushi,Shimizu, Hideaki,Hamada, Yoshitaka
, p. 119 - 122 (2007/10/03)
A method for the conversion of esters to carboxylic acids has been reported. Reaction of methyl o-methoxybenzoate with N-(trimethylsilyl)diethylamine and methyl iodide, followed by hydrolysis, afforded o-methoxybenzoic acid with a 94% yield based on 96% conversion. Methyl esters of not only aromatic acids but also aliphatic acids were converted to the corresponding acids with high yields. A combination of N-(trimethylsilyl)dimethylamine and methyl iodide was also effective to give p-methylbenzoic acid with a 85% yield based on 90% conversion from the corresponding methyl ester.
