134541-15-4 Usage
General Description
DIETHYL 2-CYANO-3-OXOSUCCINATE is a chemical compound with the molecular formula C10H13NO4. It is derived from succinic acid and is commonly used as a building block in organic synthesis. It is a colorless to pale yellow liquid with a fruity odor, and it is highly soluble in most organic solvents. DIETHYL 2-CYANO-3-OXOSUCCINATE is often used in the production of pharmaceuticals, agrochemicals, and dyes, as well as in research and development. It is important to handle this chemical with care as it may be harmful if swallowed, inhaled, or absorbed through the skin, and it can cause irritation to the eyes and respiratory system.
Check Digit Verification of cas no
The CAS Registry Mumber 134541-15-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,5,4 and 1 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 134541-15:
(8*1)+(7*3)+(6*4)+(5*5)+(4*4)+(3*1)+(2*1)+(1*5)=104
104 % 10 = 4
So 134541-15-4 is a valid CAS Registry Number.

Reaction of 2-Dimethylaminomethylene-1,3-diones with Dinucleophiles. X. Synthesis of 5-Substituted Ethyl or Methyl 4-Isoxazolecarboxylates and Methyl 4-(2,2-Dimethyl-1-oxopropyl)-5-isoxazolecarboxylate

Reaction of ethyl or methyl 2-dimethylaminomethylene-3-oxoalkanoates with hydroxylamine hydrochloride in methanol solution afforded in high yields the relative esters of 5-substituted 4-isoxazolecarboxylic acids II.These esters were hydrolyzed generally with concentrated hydrochloric acid-acetic acid mixtures to the corresponding carboxylic acids in satisfactory yields.Ethyl or methyl esters II isomerized with sodium ethoxide or methoxide, respectively, to the corresponding esters or hemiesters of 2-cyano-3-oxoalkanoic acids generally in excellent to satisfactory yields.Reaction of methyl 5,5-dimethyl-3-dimethylaminomethylene-2,4-dioxohexanoate with hydroxylamine hydrochloride afforded in moderate yield methyl 4-(2,2-dimethyl-1-oxopropyl)-5-isoxazolecarboxylate, which was converted by acid hydrolysis as above to 4-t-butyl-4-hydroxyfuroisoxazol-6-(4H)-one.
