Propiophenone, also known as 2-amino-5-fluoro-2-methoxy- (7CI,8CI), is an organic compound with the chemical formula C9H10FNO. It is a derivative of propiophenone, which is a ketone with a molecular structure consisting of a benzene ring and a three-carbon propyl chain. The 2-amino-5-fluoro-2-methoxy substitution refers to the presence of an amino group (-NH2) at the 2nd position, a fluorine atom (-F) at the 5th position, and a methoxy group (-OCH3) at the 2nd position of the benzene ring. Propiophenone, 2-amino-5-fluoro-2-methoxy- (7CI,8CI) is primarily used as an intermediate in the synthesis of various pharmaceuticals and agrochemicals, particularly in the production of selective serotonin reuptake inhibitors (SSRIs) and other antidepressant medications. Due to its potential applications in the pharmaceutical industry, it is essential to understand its chemical properties and reactivity to ensure safe and efficient synthesis processes.

Check Digit Verification of cas no

The CAS Registry Mumber 4374-20-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,7 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4374-20:
(6*4)+(5*3)+(4*7)+(3*4)+(2*2)+(1*0)=83
83 % 10 = 3
So 4374-20-3 is a valid CAS Registry Number.
