2-Chloro-5-methoxy-3-methylpyridine is a chemical compound with the molecular formula C7H8ClNO and a molecular weight of 159.7 g/mol. It is a pyridine derivative with a chlorine atom and a methoxy group attached to the 2 and 5 positions, respectively, and a methyl group at the 3 position. 2-Chloro-5-methoxy-3-methylpyridine is often used as an intermediate in the synthesis of pharmaceuticals and agrochemicals. It is also used as a building block in organic synthesis, particularly in the creation of heterocyclic compounds. 2-Chloro-5-methoxy-3-methylpyridine is generally considered to be a hazardous chemical and should be handled and stored with care to avoid adverse health effects and environmental contamination.
Check Digit Verification of cas no
The CAS Registry Mumber 74650-70-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,6,5 and 0 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 74650-70:
(7*7)+(6*4)+(5*6)+(4*5)+(3*0)+(2*7)+(1*0)=137
137 % 10 = 7
So 74650-70-7 is a valid CAS Registry Number.
