The compound's properties, such as its reactivity, solubility, and melting point, would depend on its specific structure. In summary, "C17H16" is a hydrocarbon with a potential aromatic structure, but further details are needed to fully describe its chemical nature.
The CAS Registry Mumber 6480-81-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,8 and 0 respectively; the second part has 2 digits, 8 and 1 respectively. Calculate Digit Verification of CAS Registry Number 6480-81: (6*6)+(5*4)+(4*8)+(3*0)+(2*8)+(1*1)=105 105 % 10 = 5 So 6480-81-5 is a valid CAS Registry Number.
