4-Ethoxydiazoacetophenone is an organic compound with the chemical formula C10H12N2O3. It is a derivative of diazoacetophenone, featuring an ethoxy group attached to the 4-position of the acetophenone moiety. This yellow crystalline solid is used as an intermediate in the synthesis of various organic compounds, particularly in the preparation of dyes and pharmaceuticals. It is also known for its reactivity in the Wolff rearrangement, a chemical reaction that converts diazo compounds into carbenes, which can then insert into other molecules or undergo cyclization. The compound is sensitive to light and heat, and it should be handled with care due to its potential reactivity and instability.

Check Digit Verification of cas no

The CAS Registry Mumber 6929-57-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,2 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 6929-57:
(6*6)+(5*9)+(4*2)+(3*9)+(2*5)+(1*7)=133
133 % 10 = 3
So 6929-57-3 is a valid CAS Registry Number.
