5-Chloro-3-cyanopyridine is a synthetic chemical compound that belongs to the group of organochlorines and nitriles. It is also known as 'Pyridine, 5-chloro-3-cyano-' or '3-Pyridinecarbonitrile, 5-chloro-'. This pale yellow chemical substance is utilized primarily in the field of organic synthesis, where it is a key ingredient in the manufacture of certain types of pharmaceuticals and other organic compounds. The toxicological properties of this substance have not been fully investigated, so necessary precautions should be adopted while handling it. Furthermore, this compound may also pose environmental hazards if disposed of improperly, thus requiring careful management.
Check Digit Verification of cas no
The CAS Registry Mumber 51269-82-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,2,6 and 9 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 51269-82:
(7*5)+(6*1)+(5*2)+(4*6)+(3*9)+(2*8)+(1*2)=120
120 % 10 = 0
So 51269-82-0 is a valid CAS Registry Number.

Pyrolysis of 1-substituted pyrazoles and chloroform at 550°C: Formation of α-carboline from 1-benzylpyrazoles

Pyrolysis of 13CH3 labelled 1-methylpyrazole 8 with chloroform at 550°C in a continuous flow reactor yields unlabelled 2-chloropyrimidine 9 and 2-cyanopyrrole 10 labelled at the cyano group. However, pyrolysis of 1-benzylpyrazole 14 with chloroform under similar conditions gives 9,2-phenylpyrimidine 13 and, as the major product, α-carboline 15. Pyrolysis of several substituted 1-(arylmethyl)pyrazoles and the use of 13C and 15N labelled compounds provides direct evidence by which the positions of 7 atoms of 1-benzylpyrazole can be located in the α-carboline. These data support the mechanisms suggested for the formation of 9, 10, and 15.
