It is a chlorinated pyridine derivative with an ethoxy group attached to the second position of the pyridine ring. 3-Chloro-2-ethoxypyridine is commonly used as an intermediate in the synthesis of pharmaceuticals, agrochemicals, and other organic compounds. It is a colorless to light yellow liquid with a pungent odor and is typically handled and stored under stringent safety measures due to its toxic and corrosive properties. 3-Chloro-2-ethoxypyridine is also known to be a potent irritant to the skin, eyes, and respiratory system, and should be handled with appropriate protective equipment and in a well-ventilated area.
Check Digit Verification of cas no
The CAS Registry Mumber 177743-06-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,7,7,4 and 3 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 177743-06:
(8*1)+(7*7)+(6*7)+(5*7)+(4*4)+(3*3)+(2*0)+(1*6)=165
165 % 10 = 5
So 177743-06-5 is a valid CAS Registry Number.
