Check Digit Verification of cas no

The CAS Registry Mumber 493-90-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,9 and 3 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 493-90:
83 % 10 = 3
So 493-90-3 is a valid CAS Registry Number.

Interaction of dicarboxylic metalloporphyrins with liposomes. The effect of pH on membrane binding revisited

Kepczynski, Mariusz,Ehrenberg, Benjamin

, p. 486 - 492 (2007/10/03)

The acid-base properties of Zn-hematoporphyrin IX (ZnHP) and Zn-mesoporphyrin IX (ZnMP) and the effect of pH on their binding to liposomes have been studied. The ionization constants for the two carboxylate groups of ZnHP were calculated by principal comp

The Chemistry of Pyrrolic Compounds. XLV. Haematoporphyrin Derivative: Haematoporphyrin Diacetate as the Main Product of the Reaction of Haematoporphyrin with a Mixture of Acetic and Sulfuric Acids

Clezy, Peter S.,Hai, Ton That,Henderson, Robert W.,Thuc, Le van

, p. 585 - 597 (2007/10/02)

A mixture of acetic and sulfuric acids converts haematoporphyrin into a complex mixture of porphyrins of which the main product has been characterized as the diacetate (1g).Other compounds identified in the reaction mixture were the known vinylporphyrins (1b-d), (1h) and (1i) and the isomeric monoacetoxyethyl(monohydroxyethyl)porphyrins (1l) and (1m).Analysis of the reaction mixture was complicated by the presence of 1'-ethoxyethyl derivatives (1e) or (1f), (1j) and (1k) which presumably arose by solvolysis of the corresponding acetate with ethanol present in the chloroform used for the the chromatographic separation.
