4305-26-4 Usage
General Description
Acetic acid 5-oxohexyl ester, also known as ethyl acetoacetate, is a colorless liquid with a fruity odor. It is commonly used as a solvent or intermediate in the synthesis of other chemicals, particularly in the production of pharmaceuticals, pesticides, and perfumes. This chemical is also used as a flavoring agent in food products and as a fragrance ingredient in cosmetics. Acetic acid 5-oxohexyl ester is flammable and may be harmful if swallowed, inhaled, or in contact with skin. It should be handled with caution and stored in a well-ventilated area away from heat or open flames.
Check Digit Verification of cas no
The CAS Registry Mumber 4305-26-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,0 and 5 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 4305-26:
(6*4)+(5*3)+(4*0)+(3*5)+(2*2)+(1*6)=64
64 % 10 = 4
So 4305-26-4 is a valid CAS Registry Number.

Cobalt-Catalyzed Oxidations in Volumetrically Expanded Liquids by Compressed Gases

Page/Page column 8, (2008/12/06)
Oxidations of hydrocarbons, cycloalkanes and alkenes, arylalkanes, and a variety of other organic substrates are accomplished by cobalt-N-hydroxysuccinimide co-catalyzed reactions with dioxygen under unusually mild, near ambient conditions of temperature and pressure. The improved safety of the oxidation method and the high yields of product obtained make use of a unique combination of cobalt (II) complexes with N-hydroxysuccinimide. These autoxidation reactions do not have prolonged initiation times. Many of these reactions can be safely performed under normal chemical laboratory conditions and do not require specialized equipment or reagents.
