5-ethynyl-2-Methylpyridine is a chemical compound with the molecular formula C8H7N. It is a heterocyclic aromatic compound with a pyridine ring and an ethynyl group attached to the 5th carbon atom, and a methyl group attached to the 2nd carbon atom. 5-ethynyl-2-Methylpyridine is primarily used as an intermediate in the synthesis of pharmaceuticals, agrochemicals, and other organic compounds. It has also been studied for its potential use in organic electronic devices and materials. Additionally, 5-ethynyl-2-Methylpyridine is known to have insecticidal and fungicidal properties, and has been used in the development of novel pesticides. However, it is important to handle this compound with care as it can be harmful if ingested, inhaled, or comes into contact with skin.
Check Digit Verification of cas no
The CAS Registry Mumber 1945-85-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,4 and 5 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1945-85:
(6*1)+(5*9)+(4*4)+(3*5)+(2*8)+(1*5)=103
103 % 10 = 3
So 1945-85-3 is a valid CAS Registry Number.
