General Description
5-chloro-2-(difluoroMethoxy)pyridine is a chemical compound with the molecular formula C6H3ClF2NO. It is a pyridine derivative with a chlorine atom at the 5th position and two difluoromethoxy groups at the 2nd position. This chemical is commonly used as an intermediate in the synthesis of pharmaceuticals and agrochemicals. It is also used in the manufacturing of dyes and as a solvent in organic synthesis. 5-chloro-2-(difluoroMethoxy)pyridine is considered to be a flammable liquid and should be handled with care due to its potential health hazards and environmental impacts.
Check Digit Verification of cas no
The CAS Registry Mumber 1214323-40-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,4,3,2 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1214323-40:
(9*1)+(8*2)+(7*1)+(6*4)+(5*3)+(4*2)+(3*3)+(2*4)+(1*0)=96
96 % 10 = 6
So 1214323-40-6 is a valid CAS Registry Number.

Use of fluoroform as a source of difluorocarbene in the synthesis of N-CF2H heterocycles and difluoromethoxypyridines
Thomoson, Charles S.,Wang, Linhua,Dolbier, William R.
, p. 34 - 39 (2015/03/04)
Fluoroform is used as a source of difluorocarbene to convert various N-, O-, and C-nucleophiles to their difluoromethylated derivatives. Imidazole, benzimidazole, benztriazole, hydroxypyridines, and their derivatives underwent reaction at moderate temperatures and atmospheric pressure, using potassium hydroxide as base in a two-phase (water/acetonitrile) process to provide moderate to good yields of the respective products. Nitrophenols required addition of a co-solvent (methanol) to obtain good yields of products.
