4-Nitro-benzol-(1-azo-2')-acetoacetaldehyd, also known as 4-nitrobenzenediazonium-(1-azo-2')-acetoacetaldehyde, is a complex organic compound with the chemical formula C9H7N3O4. It is characterized by the presence of a nitro group (-NO2) attached to a benzene ring, an azo group (-N=N-) connecting the benzene ring to an acetoacetaldehyde moiety. 4-Nitro-benzol-(1-azo-2')-acetoacetaldehyd is a derivative of acetoacetaldehyde, which is an important intermediate in organic synthesis, and is known for its reactivity due to the presence of the diazonium group. It is typically used in the synthesis of dyes and pigments, where the diazonium compound can couple with various coupling components to form a wide range of colored products. The compound's reactivity and the potential hazards associated with diazonium compounds require careful handling and storage, often in a cool, dry place, away from light and heat.

Check Digit Verification of cas no

The CAS Registry Mumber 2011-47-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,1 and 1 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2011-47:
(6*2)+(5*0)+(4*1)+(3*1)+(2*4)+(1*7)=34
34 % 10 = 4
So 2011-47-4 is a valid CAS Registry Number.
