The chemical compound "o-F-C6H4CH2CH(Me)NHNH2" is a derivative of aniline, featuring a fluorine atom at the ortho position relative to the amino group. This fluorinated aniline has a molecular structure that includes a benzene ring with a fluorine atom attached to the second carbon (hence the "o-F"), followed by an ethyl group (CH2CH2), a methyl group (Me), and a secondary amine group (NHNH2). The presence of the fluorine atom can significantly influence the compound's reactivity and physical properties, such as electronegativity and lipophilicity, making it a potentially important moiety in the design of pharmaceuticals and other chemical applications where specific electronic or steric effects are desired.
The CAS Registry Mumber 704-72-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,0 and 4 respectively; the second part has 2 digits, 7 and 2 respectively. Calculate Digit Verification of CAS Registry Number 704-72: (5*7)+(4*0)+(3*4)+(2*7)+(1*2)=63 63 % 10 = 3 So 704-72-3 is a valid CAS Registry Number.
