Check Digit Verification of cas no

The CAS Registry Mumber 588727-73-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,8,8,7,2 and 7 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 588727-73:
(8*5)+(7*8)+(6*8)+(5*7)+(4*2)+(3*7)+(2*7)+(1*3)=225
225 % 10 = 5
So 588727-73-5 is a valid CAS Registry Number.

Palladium-catalyzed synthesis of nonsymmetrically functionalized bipyridines, poly(bipyridines) and terpyridines

Puglisi, Alessandra,Benaglia, Maurizio,Roncan, Giulia

, p. 1552 - 1558 (2003)

Palladium-catalyzed coupling reactions were employed to prepare nonsymmetric, densely functionalized bipyridines and oligo(bipyridines), featuring sensitive functionalities like alcohol, ester and aldehyde groups. Stille coupling between halo (poly)pyridine and the proper (poly)pyridyltin derivative afforded in good yields nonsymmetric, derivatized oligo(bipyridines), amenable to further synthetic modifications. The methodology was used also to synthesize highly functionalized terpyridines. A series of Suzuki and Stille palladium-promoted coupling reactions allowed us to obtain in good yields terpyridines bearing two different and differently functionalizable groups, valuable building blocks for the construction of complex supramolecular frameworks.
