Check Digit Verification of cas no

The CAS Registry Mumber 850089-99-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,0,0,8 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 850089-99:
(8*8)+(7*5)+(6*0)+(5*0)+(4*8)+(3*9)+(2*9)+(1*9)=185
185 % 10 = 5
So 850089-99-5 is a valid CAS Registry Number.

Facile synthesis of 6-aryl-3-pyridyl-1,2,4-triazines as a key step toward highly fluorescent 5-substituted bipyridines and their Zn(II) and Ru(II) complexes

Kozhevnikov, Valery N.,Shabunina, Olga V.,Kopchuk, Dmitry S.,Ustinova, Maria M.,K?nig, Burkhard,Kozhevnikov, Dmitry N.

, p. 8963 - 8973 (2008/12/22)

A wide series of substituted bipyridines were obtained through the synthesis of 1,2,4-triazines and their aza Diels-Alder reactions. The reported method facilitates the synthesis of functionally diverse bipyridines that provides fine-tuning of photophysical properties of new ligands and their Zn(II) and Ru(II) complexes. Some of substituted bipyridines exhibit 'off-on' fluorescence response toward Zn2+ cations.

An efficient route to 5-(hetero)aryl-2,4′- and 2,2′-bipyridines through readily available 3-pyridyl-1,2,4-triazines

Kozhevnikov, Valery N.,Kozhevnikov, Dmitry N.,Shabunina, Olga V.,Rusinov, Vladimir L.,Chupakhin, Oleg N.

, p. 1791 - 1793 (2007/10/03)

A new route to substituted bipyridines based on a new method for the synthesis of substituted 3-pyridyl-1,2,4-triazines and their aza-Diels-Alder reactions is shown to be an efficient strategy for the preparation of structurally diverse bipyridine ligands.
