Check Digit Verification of cas no

The CAS Registry Mumber 522644-14-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,2,2,6,4 and 4 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 522644-14:
(8*5)+(7*2)+(6*2)+(5*6)+(4*4)+(3*4)+(2*1)+(1*4)=130
130 % 10 = 0
So 522644-14-0 is a valid CAS Registry Number.

Synthesis of linear and cyclic hexapeptides with Nε-(1,2-dihydro-1-hydroxy-2-oxopyrimidin-4-yl) -L-lysyl-β-alanyl as the repeating unit and properties of their iron(III) complexes

, p. 371 - 381 (2007/10/03)

Linear and cyclic hexapeptides including Nε(1,2-dihydro-1-hydroxy-2-oxopyrimidin-4-yl) -L-lysyl-β-alanyl as the repeating unit have been synthesized. These hexapeptides formed 1:1 iron(III) complexes; λmax 466 nm and ε 4700 for a linear hexapeptide (8), and λmax 458 nm and ε 4300 for a cyclic hexapeptide (9). The relative stability constants of 8- and 9-iron(III) complexes were estimated to be 26.1 and 28.0, respectively. A linear hexapeptide (8)-iron(III) complex predominantly existed in Δ-configuration. From kinetic data on iron(III) removal from human transferrin, a linear hexapeptides (8) was found to efficiently remove three times as much iron(III) from transferrin as desferrioxamine B, only a chemotherapeutic agent for the iron overload disease.
