1-[5-(2,2,2-Trichloroacetyl)-1H-pyrrol-3-yl]-1-butanone is a complex chemical compound that belongs to the class of organic compounds known as pyrroles. Pyrroles are compounds that contain a five-membered aromatic ring which consists of one nitrogen atom and four carbon atoms. The mentioned chemical compound has a molecular structure that includes a butanone group, a pyrrol ring, and a trichloroacetic acid residue which contributes to its unique properties. The specific details of its physical characteristics, toxicity, handling precautions, uses, or production methods would likely require a more thorough scientific examination or analysis.
Check Digit Verification of cas no
The CAS Registry Mumber 111468-91-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,4,6 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 111468-91:
(8*1)+(7*1)+(6*1)+(5*4)+(4*6)+(3*8)+(2*9)+(1*1)=108
108 % 10 = 8
So 111468-91-8 is a valid CAS Registry Number.

The Friedel-Crafts acylation of ethyl pyrrole-2-carboxylate (3) was studied under several conditions using various Lewis acids and acyl chlorides. The acylation with various acyl chlorides in the presence of aluminum chloride gave exclusively ethyl 4-acylpyrrole-2-carboxylate (5), whereas weaker Lewis acids such as zinc chloride and boron trifluoride etherate gave a mixture of ethyl 4- and 5-acylpyrrole-2-carboxylates.
