Diethyl malonate, also known as 2-(3)H1-diethyl malonate, is an organic compound with the chemical formula C7H12O4. It is a colorless liquid that is soluble in water and has a slight, pleasant odor. Diethyl malonate is a valuable intermediate in the synthesis of various organic compounds, particularly in the preparation of barbiturates, pyrimidines, and other heterocyclic compounds. It is produced by the condensation of diethyl oxalate with ethanol in the presence of a base, such as sodium ethoxide. The compound is also used as a reagent in the malonic ester synthesis, a method for the preparation of carboxylic acids. Due to its reactivity, diethyl malonate is handled with care, as it can be harmful if inhaled, ingested, or absorbed through the skin.

Check Digit Verification of cas no

The CAS Registry Mumber 4286-16-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,8 and 6 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 4286-16:
(6*4)+(5*2)+(4*8)+(3*6)+(2*1)+(1*6)=92
92 % 10 = 2
So 4286-16-2 is a valid CAS Registry Number.
