2917-64-8 Usage
General Description
Ethyl(dimethyl)silyl methyl acetate, also known as EDSMA, is a chemical compound commonly used as a reagent in organic synthesis. It is a clear, colorless liquid with a slightly sweet, fruity odor. EDSMA is classified as an alkyltrimethylsilyl ether, and it is commonly used as a protecting group for alcohols and phenols in organic chemistry. The compound is highly reactive and can undergo a variety of chemical reactions, including hydrolysis, alcoholysis, and rearrangement. EDSMA is widely used in the pharmaceutical and agrochemical industries as a versatile intermediate in the synthesis of various compounds. It is important to handle EDSMA with caution, as it is flammable and can be harmful if ingested, inhaled, or absorbed through the skin.
Check Digit Verification of cas no
The CAS Registry Mumber 2917-64-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,1 and 7 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2917-64:
(6*2)+(5*9)+(4*1)+(3*7)+(2*6)+(1*4)=98
98 % 10 = 8
So 2917-64-8 is a valid CAS Registry Number.

Synthesis and thermal stability of silicon-containing esters of phosphorus acids 5.* the relative migration ability of substituents at the silicon atom in the thermal rearrangement of trialkylsilylmethyl diphenyl phosphates
Zakharov,Molchanova,Shcherbina,Petrovskii,Kabachnik
, p. 1718 - 1724 (2007/10/03)
A number of trialkylsilylmethyl diphenyl phosphates MeRR'SiCH2OP(O)(OPh)2 (Ia-e: R = Et (a), Pr (b), CF3CH2CH2 (c, e), Me3SiCH2 (d); R' = Me (a-d), Et (e)) were synthesized and their thermal rearrangement, of the 1,2-shift type, was studied. The rearrangement consists of the migration of an alkyl group from Si atom to the methylene carbon atom and gives the corresponding silyl esters. The rate of the rearrangement was found to increase in the order 1d 3CH2CH2 3SiCH2, which differs substantially from the order in which the rate of the rearrangement of phosphates 1a-d changes. The electro-negativity of the migrating group affects noticeably the relative ability to migrate.
