Check Digit Verification of cas no

The CAS Registry Mumber 890936-07-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,0,9,3 and 6 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 890936-07:
(8*8)+(7*9)+(6*0)+(5*9)+(4*3)+(3*6)+(2*0)+(1*7)=209
209 % 10 = 9
So 890936-07-9 is a valid CAS Registry Number.

Synthesis of a novel ditopic ligand incorporating directly bonded 1,10-phenanthroline and 2,2′:6′,2″-terpyridine units

Gavi?a, Pablo,Tatay, Sergio

, p. 3471 - 3473 (2006)

The synthesis of a rigid ditopic ligand incorporating a 1,10-phenanthroline directly connected through its 3-position to the 5-position of a 2,2′:6′,2″-terpyridine is described. The synthesis is based on a series of palladium(0)-catalyzed cross-coupling reactions (Stille and Suzuki couplings) starting from 1,10-phenanthroline and bromo-substituted pyridines.
