Check Digit Verification of cas no
The CAS Registry Mumber 635684-02-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,5,6,8 and 4 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 635684-02:
(8*6)+(7*3)+(6*5)+(5*6)+(4*8)+(3*4)+(2*0)+(1*2)=175
175 % 10 = 5
So 635684-02-5 is a valid CAS Registry Number.

New multidentate pyrazolyl-pyridine ligands - Synthesis and structures
Bell, Zoee R.,McCleverty, Jon A.,Ward, Michael D.
, p. 665 - 670 (2003)
Five new multidentate ligands have been prepared containing N,N-bidentate pyrazolyl-pyridine units linked to a central aromatic spacer unit. The ligands 3,3′-bis(3-{pyridin-2-yl}-pyrazol-1-yl-methyl)-p-terphenyl (I), 4,4′-bis(3-{pyridin-2-yl}-pyrazol-1-yl
