Check Digit Verification of cas no

The CAS Registry Mumber 720715-38-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,2,0,7,1 and 5 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 720715-38:
(8*7)+(7*2)+(6*0)+(5*7)+(4*1)+(3*5)+(2*3)+(1*8)=138
138 % 10 = 8
So 720715-38-8 is a valid CAS Registry Number.

Synthesis and characterization of cyclopentadienylruthenium(II) complexes containing N,N′-donor Schiff base ligands: Crystal and molecular structure of [(η5-C5H5)Ru(C5H 4N-2-CH=N-C6H4-p-OCH3)(PPh 3)]PF6

, p. 1567 - 1572 (2008/10/09)

Complexes of the formulae [(η5-C5H 5)Ru(PPh3)(C5H5N-2-CH=N-C 6H4-p-X)]+ [X=H (2a), CH3 (2b), OCH3 (2c), Cl (2d), NO2 (2e)] and [(η5- C5H5)Ru(PPh3)(C5H 5N-2-CH=N-C6H11)]+ (3) were prepared by reacting para-substituted N-(pyrid-2-ylmethylene)-phenylamines (2-PP) and N-(pyrid-2-ylmethylene)cyclohexylamine (2-PC) with [(η5-C 5H5)Ru(PPh3)2Cl] (1) in methanol. These complexes have been isolated as hexa-fluorophosphate salts. Representative complex 2c has been established by single crystal X-ray diffraction analysis. Complex 2c crystallizes in the orthorhombic space group Pbcn, with a=21.1560 (11) A?, b=18.3972 (9) A? and c=17.5130 (9) A?, V=6816.3 (6) A?3 and z=8. All these complexes were characterized by FT-IR, 1H NMR and 31P{1H} NMR spectroscopy.
