Pentanoic acid, 2-acetyl-3-methyl-5-oxo-, ethyl ester, also known as ethyl 2-acetyl-3-methyl-5-oxopentanoate, is a chemical compound with the molecular formula C9H14O4. It is an ester derivative of pentanoic acid, characterized by the presence of an acetyl group (CH3CO-) at the 2-position, a methyl group (CH3-) at the 3-position, and a 5-oxo (carbonyl) group. This organic compound is formed by the esterification of the corresponding pentanoic acid with ethanol, resulting in an ester linkage between the carboxylic acid group and the ethyl group (C2H5-). Ethyl 2-acetyl-3-methyl-5-oxopentanoate is a colorless liquid with a fruity odor and is used in the synthesis of various fragrances and flavorings, particularly in the food and pharmaceutical industries.

Check Digit Verification of cas no

The CAS Registry Mumber 3400-77-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,0 and 0 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3400-77:
(6*3)+(5*4)+(4*0)+(3*0)+(2*7)+(1*7)=59
59 % 10 = 9
So 3400-77-9 is a valid CAS Registry Number.
