Check Digit Verification of cas no

The CAS Registry Mumber 15750-73-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,7,5 and 0 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 15750-73:
(7*1)+(6*5)+(5*7)+(4*5)+(3*0)+(2*7)+(1*3)=109
109 % 10 = 9
So 15750-73-9 is a valid CAS Registry Number.

Extended coordination frameworks incorporating heterobimetallic squares

Vreshch, Volodimir D.,Lysenko, Audrey B.,Chernega, Alexander N.,Howard, Judith A.K.,Krautscheid, Harald,Sieler, Joachim,Domasevitch, Konstantin V.

, p. 2899 - 2903 (2004)

The molecular structure of aluminium and iron(III) complexes with 3-phenyl and 3-(4-pyridyl) (HL) substituted acetylacetonate ligands is appreciably distorted. For AlL3 and FeL3 this shows that the orientation of the side pyridyl-N donor atoms lone pairs is about 90 and 135° which favours the assembly of heterobimetallic square patterns in Al(Fe)L3 complexes with metal ions. This was employed for the modular construction of semi-regular heterobimetallic networks, in which the pyridyldiketonate ligands bridge pairs of Fe(Al)/Cd(Co) metal ions and support the structure of 1D and 2D coordination polymers. The unprecedented 2D structure of [Cd{AlL3}(CH3OH){NO3} 2]·2CHCl3 and Cd{AlL3}-(CH 3OH)Br2]·2CHCl3·2CH 3OH is based upon plane tiling by a set of heterobimetallic squares and octagons, while [Cd{FeL3}2(NO3) 2]·2H2O and [Co{AlL3}2Cl 2]·4CHCl3·2CH3OH are 1D polymers and exist as chains of heterobimetallic squares sharing opposite vertices.
