32933-03-2 Usage
General Description
Ethyl 1-acetylcyclopropanecarboxylate, also known as ethyl 2-acetylcyclopropanecarboxylate, is a chemical compound with the molecular formula C8H12O3. It is a clear, colorless liquid with a fruity odor, and is commonly used as a flavoring agent in the food industry. ethyl 1-acetylcyclopropanecarboxylate is also used in the synthesis of various pharmaceuticals and agricultural chemicals. It is considered to be relatively stable under normal conditions, but may react violently with strong oxidizing agents. Ethyl 1-acetylcyclopropanecarboxylate is also considered to be a potential irritant to the skin, eyes, and respiratory system, and should be handled with care in a controlled environment.
Check Digit Verification of cas no
The CAS Registry Mumber 32933-03-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,9,3 and 3 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 32933-03:
(7*3)+(6*2)+(5*9)+(4*3)+(3*3)+(2*0)+(1*3)=102
102 % 10 = 2
So 32933-03-2 is a valid CAS Registry Number.

An efficient and practical synthesis of 2′,3′-nonsubstituted cyclohexane-1,3-dione-2-spirocyclopropanes using a sulfonium salt was achieved. The reaction of 1,3-cyclohexanediones and (2-bromoethyl)diphenylsulfonium trifluoromethanesulfonate with powdered K2CO3 in EtOAc at room temperature (r.t.) provided the corresponding spirocyclopropanes in high yields. The synthetic method was also applied to 1,3-cyclopentanedione, 1,3-cycloheptanedione, 1,3-indanedione, acyclic 1,3-diones, ethyl acetoacetate, and Meldrum's acid.
