General Description
2-Chloro-4,6-dimethyl-nicotinonitrile is a chemical compound that is used in the production of various pharmaceuticals and agrochemicals. It is a chlorinated derivative of nicotinonitrile, and its structure consists of a chloro group, two methyl groups, and a cyano group attached to the nicotinonitrile ring. 2-Chloro-4,6-dimethyl-nicotinonitrile is an important intermediate in the synthesis of various drugs and pesticides due to its versatile reactivity and ability to undergo different chemical transformations. Its uses include the creation of new medicinal compounds and herbicides for agricultural applications. However, it is essential to handle this chemical with care, as it is toxic and can cause irritation if it comes into contact with the skin or eyes.
Check Digit Verification of cas no
The CAS Registry Mumber 58850-81-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,8,5 and 0 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 58850-81:
(7*5)+(6*8)+(5*8)+(4*5)+(3*0)+(2*8)+(1*1)=160
160 % 10 = 0
So 58850-81-0 is a valid CAS Registry Number.

A series of stable 2-alkoxycarbonyl enamino thioaldehydes (2a-g) were synthesized by solvolysis of the Vilsmeier salts (1) with aqueous or methanolic sodium hydrogen sulphide. Three 2-alkoxycarbonyl enamino selenaldehydes were obtained as the pentacarbonyltungsten(o) complexes (7a-c). The 2-cyano and simple enamino thioaldehydes (3a-m) and (6a-j) (including some new homologues obtained by an improved synthetic method) are described. Some reactions of 2-cyano and 2-alkoxycarbonyl enamino thioaldehydes were examined e.g. oxidation with MCPBA to give the isothiazoles (8). The symmetrically tetrasubstituted pyridines (9) were produced by bimolecular cyclisation under acidic conditions: hydrolysis in acidic 95% aq. EtOH gave the enamino aldehydes (11) and aroylacetonitriles (12) together with (9). The imines (13) were formed in good yield on reaction with primary amines.
