1-(3-Chloro-phenyl)-4,6-dimethyl-2-oxo-1,2-dihydro-pyridine-3-carbonitrile is a complex organic compound with the molecular formula C14H11ClN2O. It features a pyridine ring, which is a six-membered aromatic ring containing one nitrogen atom, and a carbonitrile group (CN) attached to the third position. The compound also has a 3-chlorophenyl group attached to the first position of the pyridine ring, and two methyl groups (CH3) at the fourth and sixth positions. The 2-oxo part of the name indicates the presence of a carbonyl group (C=O) at the second position. This chemical is known for its potential applications in the synthesis of pharmaceuticals and agrochemicals, particularly as an intermediate in the production of certain pesticides and other chemical compounds. Its structure and properties make it a versatile building block in organic synthesis, though it should be handled with care due to its potential toxicity and reactivity.

Check Digit Verification of cas no

The CAS Registry Mumber 24522-57-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,5,2 and 2 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 24522-57:
(7*2)+(6*4)+(5*5)+(4*2)+(3*2)+(2*5)+(1*7)=94
94 % 10 = 4
So 24522-57-4 is a valid CAS Registry Number.

Ionic liquid catalyzed 4,6-disubstituted-3-cyano-2-pyridone synthesis under solvent-free conditions

Chavan, Sunil S.,Degani, Mariam S.

experimental part, p. 1693 - 1697 (2012/03/11)

A green protocol for the synthesis of 4,6-disubstituted-3-cyano-2-pyridones from cyanoacetamides and 1,3-dicarbonyl compounds or chalcones using guanidine based ionic liquid as catalyst has been developed. In solvent-free conditions at 30 °C, [TMG][Lac] (1,1,3,3-tetramethylguanidine lactate) was found to have the highest catalytic activity among the ionic liquids including [TMG][Ac] (1,1,3,3-tetramethylguanidine acetate), [TMG][Pr] (1,1,3,3-tetramethylguanidine propionate), [TMG][n-Bu] (1,1,3,3-tetramethylguanidine n-butyrate) and [TMG][TFA] (1,1,3,3-tetramethylguanidine trifluoroacetate). The catalyst was recovered and recycled several times without significant loss of catalytic activity. Graphical Abstract: [Figure not available: see fulltext.]
