Check Digit Verification of cas no

The CAS Registry Mumber 727990-94-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,2,7,9,9 and 0 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 727990-94:
(8*7)+(7*2)+(6*7)+(5*9)+(4*9)+(3*0)+(2*9)+(1*4)=215
215 % 10 = 5
So 727990-94-5 is a valid CAS Registry Number.

Tetranuclear bismuth complex Bi4(O)2(O 2CC6H2F3-3,4,5,)8· 2η6-C6H5Me: Synthesis and structure

Sharutin,Egorova,Sharutina,Ivanenko,Adonin,Starichenko,Pushilin,Gerasimenko

, p. 838 - 844 (2003)

Tetranuclear organobismuth complex Bi4(O)2(O 2CC6H2F3-3,4,5)8· 2η6-C6H5Me with four bismuth atoms joined via the bridging carboxylate ligands and oxygen atoms was studied using X-ray diffraction analysis. The coordination sphere of either of the two terminal bismuth atoms contains the chelate carboxylate ligand and the toluene molecule. For the bridging tricoordinated oxygen atoms, the Bi-O distances are 2.083(2), 2.119(2), and 2.276(2) A. The average distance between the bismuth atom and the center of toluene molecule is equal to 3.131 A.
