3-4-diethoxypropiophenone, also known as 1-(3,4-diethoxyphenyl)-2-propanone, is an organic compound with the molecular formula C13H18O3. It is a colorless to pale yellow liquid with a mild, sweet odor. This chemical is primarily used as a synthetic intermediate in the production of various pharmaceuticals, agrochemicals, and other organic compounds. It is synthesized through the Friedel-Crafts acylation of anisole with propionyl chloride in the presence of a Lewis acid catalyst, such as aluminum chloride. Due to its reactivity and potential use in the synthesis of controlled substances, 3-4-diethoxypropiophenone is subject to regulatory controls in some countries.

Check Digit Verification of cas no

The CAS Registry Mumber 720-66-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,2 and 0 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 720-66:
(5*7)+(4*2)+(3*0)+(2*6)+(1*6)=61
61 % 10 = 1
So 720-66-1 is a valid CAS Registry Number.
