The chemical compound "(C20H8N4Ph4C2(p-C6H4Cl)2H)Cl" is a complex organic molecule with a molecular formula that indicates it contains 20 carbon (C) atoms, 8 hydrogen (H) atoms, 4 nitrogen (N) atoms, 4 phenyl (Ph) groups, 2 carbon atoms in a C2 unit, 2 para-chlorophenyl (p-C6H4Cl) groups, and one additional hydrogen atom, with a final chloride (Cl) ion. (C20H8N4Ph4C2(p-C6H4Cl)2H)Cl is likely a derivative of a porphyrin or a related macrocyclic structure, given the presence of nitrogen and phenyl groups, which are common in such structures. The para-chlorophenyl groups suggest that there are chlorine atoms attached to the phenyl rings at the para position. The overall structure is likely to be a large, conjugated system with potential applications in areas such as materials science, pharmaceuticals, or as a dye due to its complex aromatic structure and potential for strong coloration.
The CAS Registry Mumber 79311-04-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,3,1 and 1 respectively; the second part has 2 digits, 0 and 4 respectively. Calculate Digit Verification of CAS Registry Number 79311-04: (7*7)+(6*9)+(5*3)+(4*1)+(3*1)+(2*0)+(1*4)=129 129 % 10 = 9 So 79311-04-9 is a valid CAS Registry Number.
