The term "3-phenyl-" refers to a chemical structure where a phenyl group (a benzene ring with a hydrogen atom removed) is attached to the third carbon atom of a molecule. This functional group is commonly found in various organic compounds, such as 3-phenylpropionic acid, 3-phenyl-1-propanol, and 3-phenylpyridine. The presence of the 3-phenyl group can significantly influence the physical, chemical, and biological properties of the molecule, affecting aspects like solubility, reactivity, and potential applications in pharmaceuticals, materials science, and other fields. The specific impact of the 3-phenyl group depends on the rest of the molecule and the context in which it is used.
The CAS Registry Mumber 4445-49-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,4 and 5 respectively; the second part has 2 digits, 4 and 9 respectively. Calculate Digit Verification of CAS Registry Number 4445-49: (6*4)+(5*4)+(4*4)+(3*5)+(2*4)+(1*9)=92 92 % 10 = 2 So 4445-49-2 is a valid CAS Registry Number.
