Check Digit Verification of cas no

The CAS Registry Mumber 32091-51-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,0,9 and 1 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 32091-51:
(7*3)+(6*2)+(5*0)+(4*9)+(3*1)+(2*5)+(1*1)=83
83 % 10 = 3
So 32091-51-3 is a valid CAS Registry Number.

Nickel-catalyzed synthesis of oxazoles via C-S activation

Lee, Kyoungsoo,Counceller, Carla M.,Stambuli, James P.

supporting information; experimental part, p. 1457 - 1559 (2009/08/08)

The synthesis of 2-substituted oxazoles is achieved via nickel-catalyzed cross-coupling reaction of 2-methylthio-oxazole and various organozinc reagents. An extension of this method is demonstrated with a chemoselective, one-pot synthesis of unsymmetrical

Compounds containing a N-heteroaryl moiety linked to fused ring moieties for the inhibition of NAD(P)H oxidases and platelet activation

-

Page/Page column 87, (2008/06/13)

The invention relates to compounds containing a N-heteroaryl moiety, which is linked via oxygen, sulfur or nitrogen, or via a methylene bridge and oxygen, sulfur or nitrogen to a fused ring moiety, in particular to the 1,2,3-triazolo[4,5-d]pyrimidine-7-yl radical. The invention also relates to a process for the preparation of said compounds and the use thereof in drugs for the treatment of NAD(P)H oxidases-related diseases and disorders and inhibition of platelet activation.
