"10-(4-hexadecyloxycarbonylphenyl)-5,15,20-tris<4-carboxyphenyl>-21H,23H-phorphine trihydrate" is a complex organic compound with a molecular formula of C72H54N4O12.3H2O. 10-(4-hexadecyloxycarbonylphenyl)-5,15,20-tris<4-carboxyphenyl>-21H,23H-phorphine trihydrate is a derivative of the porphyrin macrocycle, which is a large heterocyclic organic molecule with a structure similar to that of heme, the non-protein part of hemoglobin. The specific structure of 10-(4-hexadecyloxycarbonylphenyl)-5,15,20-tris<4-carboxyphenyl>-21H,23H-phorphine trihydrate features a central porphyrin ring system, with three 4-carboxyphenyl groups attached at positions 5, 15, and 20, and a 4-hexadecyloxycarbonylphenyl group at position 10. The compound also contains three water molecules (trihydrate) as part of its crystal structure. This type of porphyrin derivative is often studied for its potential applications in areas such as photodynamic therapy, where its ability to absorb light and generate reactive oxygen species can be harnessed for the treatment of certain diseases.
The CAS Registry Mumber 74681-89-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,6,8 and 1 respectively; the second part has 2 digits, 8 and 9 respectively. Calculate Digit Verification of CAS Registry Number 74681-89: (7*7)+(6*4)+(5*6)+(4*8)+(3*1)+(2*8)+(1*9)=163 163 % 10 = 3 So 74681-89-3 is a valid CAS Registry Number.
