"4',4'''-diamino-" refers to a chemical structure where two amino groups (-NH2) are attached to the 4' and 4''' positions of a molecule, typically in a biphenyl or similar compound. This specific arrangement of amino groups can significantly influence the molecule's properties, such as its reactivity, solubility, and potential applications in various fields, including pharmaceuticals, dyes, and materials science. The presence of these amino groups can also affect the molecule's ability to form hydrogen bonds and its overall stability.
The CAS Registry Mumber 4828-90-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,2 and 8 respectively; the second part has 2 digits, 9 and 0 respectively. Calculate Digit Verification of CAS Registry Number 4828-90: (6*4)+(5*8)+(4*2)+(3*8)+(2*9)+(1*0)=114 114 % 10 = 4 So 4828-90-4 is a valid CAS Registry Number.
