Check Digit Verification of cas no

The CAS Registry Mumber 149792-13-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,7,9 and 2 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 149792-13:
(8*1)+(7*4)+(6*9)+(5*7)+(4*9)+(3*2)+(2*1)+(1*3)=172
172 % 10 = 2
So 149792-13-2 is a valid CAS Registry Number.

Synthesis and antitumor properties of an anthraquinone bisubstituted by the copper chelating peptide Gly-Gly-L-His

Morier-Teissier,Boitte,Helbecque,Bernier,Pommery,Duvalet,Fournier,Hecquet,Catteau,Henichart

, p. 2084 - 2090 (1993)

A new molecule 4 [(GGH-DAE)2DHQ] associating the 1,4,5,8- tetrahydroxyanthraquinone ring (DHQ) of the antitumor drug mitoxantrone (2), two diaminoethylene chains (DAE), and the metal-chelating peptide Gly-Gly- His (GGH) has been synthesized. Such a molecule presents characteristics able to induce antitumor activity: compound 4 intercalates into DNA as measured by ΔT(m), fluorescence quenching, and viscometry; ESR studies demonstrate that several types of Cu complexes are formed depending on pH; and the production of free radicals, as evidenced by spin-trapping, is enhanced by 4. In vitro, in leukemia cells L1210 and mammary cells MCF7, 4 is slightly less cytostatic than mitoxantrone, but substantially less toxic. In vivo, in leukemia P388 on mice, a T/C value of 230 is obtained at 25 mg/kg, higher than the one of mitoxantrone, which is toxic at the same dose.
