Check Digit Verification of cas no

The CAS Registry Mumber 1217890-38-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,7,8,9 and 0 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1217890-38:
(9*1)+(8*2)+(7*1)+(6*7)+(5*8)+(4*9)+(3*0)+(2*3)+(1*8)=164
164 % 10 = 4
So 1217890-38-4 is a valid CAS Registry Number.

1,3-Diphenylindenyl zirconium complexes. Synthesis, structure, and reduction reactions

Belov,Krut'Ko,Kirsanov,Lemenovskii,Churakov

, p. 1657 - 1660 (2008)

New zirconium sandwich complexes (η5-C9H 5Ph2)2ZrCl2 (1) and (η5-C9H5Ph2)-(η5- C5(CH3)5)ZrCl2 (2) were synthesized and characterized. The molecular structures of complexes 1 and 2 were established by X-ray diffraction. The reduction of 1 and 2 does not stop at the formation of the ZrII derivatives with the η9- coordinated indenyl ligand; instead the reaction results in the destruction of the metallocene structure.
