General Description
2,4-Dichloro-N-(2-hydroxyethyl)benzenecarboxamide is a chemical compound with the molecular formula C9H9Cl2NO2. It's also known as 2,4-Dichloro-N-(2-hydroxyethyl)benzoic acid amide. This chemical falls under the category of an aromatic amide and is characterized by the presence of two chlorine atoms on a benzene ring, along with a carboxamide group and a hydroxyethyl group. It has significant applications in the field of organic chemistry. However, the toxicity, hazards, and handling precautions are not well established and it must be handled with care following standard guidelines for chemical substances.
Check Digit Verification of cas no
The CAS Registry Mumber 20656-08-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,6,5 and 6 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 20656-08:
(7*2)+(6*0)+(5*6)+(4*5)+(3*6)+(2*0)+(1*8)=90
90 % 10 = 0
So 20656-08-0 is a valid CAS Registry Number.

Microwave-Assisted Synthesis of 2-Aryl-2-oxazolines, 5,6-Dihydro-4H-1,3-oxazines, and 4,5,6,7-Tetrahydro-1,3-oxazepines

The first general procedure for the synthesis of 5- to 7-membered cyclic iminoethers by microwave-assisted cyclization of ω-amido alcohols promoted by polyphosphoric acid (PPA) esters is presented. 2-Aryl-2-oxazolines and 5,6-dihydro-4H-1,3-oxazines were efficiently prepared using ethyl polyphosphate/CHCl3. Trimethylsilyl polyphosphate in solvent-free conditions allowed for the synthesis of hitherto-unreported 4,5,6,7-tetrahydro-1,3-oxazepines. The method involves good to excellent yields and short reaction times.The reaction mechanism and the role of PPA esters were investigated in a chiral substrate.
