Diethylmethylsilyl acetate, also known as (diethylmethylsilyl)oxy-acetate, is an organosilicon compound with the chemical formula C7H16O2Si. It is a colorless liquid that is soluble in organic solvents and is commonly used as a protecting group in organic synthesis, particularly in the protection of carboxylic acids. The molecule consists of a central silicon atom bonded to three alkyl groups (two ethyl and one methyl) and an acetate group. Diethylmethylsilyl acetate is stable under various reaction conditions and can be easily removed under mild acidic or basic conditions, making it a valuable reagent in the synthesis of complex organic molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 5290-28-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,9 and 0 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 5290-28:
(6*5)+(5*2)+(4*9)+(3*0)+(2*2)+(1*8)=88
88 % 10 = 8
So 5290-28-8 is a valid CAS Registry Number.
