Check Digit Verification of cas no

The CAS Registry Mumber 1017-99-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,1 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1017-99:
(6*1)+(5*0)+(4*1)+(3*7)+(2*9)+(1*9)=58
58 % 10 = 8
So 1017-99-8 is a valid CAS Registry Number.

Synthesis, characterization, and molecular structures of di- and triorganotin(IV) complexes with 9-anthracenecarboxylic acid: The structural diversity in organotin 9-anthracenecarboxylates

Amini, Mostafa M.,Azadmeher, Amirreza,Khavasi, Hamid Reza,Ng

, p. 3922 - 3930 (2008/02/09)

The di- and triorganotin(IV) derivatives of anthracenecarboxylic acid, Ph2MeSnOC(O)C14H9 (2), Me3SnOC(O)C14H9 (3), Me2Sn[OC(O)C14H9]2 · CH3OH (4) Ph3SnOC(O)C14H9 · CH3OH (5), Ph2EtSnOC(O)C14H9 (6), Ph2Sn[OC(O)(C14H9)]2 (7) and PhMe2SnOC(O)C14H9 (8) were synthesized by the reaction of Ph2MeSnI, Me3SnCl, Me2SnCl2, Ph3SnCl, Ph2EtSnI, Ph2SnCl2, and PhMe2SnI with 9-anthracenecarboxylic acid, respectively, with the aid of potassium iso-propoxide. All complexes were characterized by elemental analysis, mass spectrometry, IR, 1H, 13C and 119Sn NMR spectroscopes. The molecular structures of complexes 2, 3 and 4 were determined by single crystal X-ray analysis. The X-ray structures reveal that complex 2 and 3 adopt a polymeric trans-C3SnO2 trigonal bipyamidal configuration with the oxygen atoms occupying axial positions. Complex 4 adopts a monomeric structure with two carboxylates coordinated to tin in a monodentate form from axial and equatorial positions, and with the coordination number raised to five as the methanol occupies the apical position of the trigonal bipyramid.
