Check Digit Verification of cas no

The CAS Registry Mumber 3476-89-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,7 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 3476-89:
(6*3)+(5*4)+(4*7)+(3*6)+(2*8)+(1*9)=109
109 % 10 = 9
So 3476-89-9 is a valid CAS Registry Number.

Rhodium-catalyzed transfer hydrogenation of quinoxalines with water as a hydrogen source

Zhang, Xia,Chen, Jingchao,Khan, Ruhima,Shen, Guoli,He, Zhenxiu,Zhou, Yongyun,Fan, Baomin

Rhodium-catalyzed transfer hydrogenation of quinoxalines with water as a hydrogen source was reported. The reaction allowed the simple preparation of tetrahydroquinoxalines under mild conditions. The deuterium-labelling experiment confirmed that water is

Iridium-catalyzed condensation of amines and vicinal diols to substituted piperazines

Lorentz-Petersen, Linda L. R.,Nordstrom, Lars Ulrik,Madsen, Robert

, p. 6752 - 6759 (2013/01/15)

A straightforward procedure is described for the synthesis of piperazines from amines and 1,2-diols. The heterocyclization is catalyzed by [Cp*IrCl2]2 and sodium hydrogen carbonate and can be achieved with either toluene or water as solvent. The transformation does not require any stoichiometric additives and only produces water as the byproduct. The reaction can be performed between a 1,2-diamine and a 1,2-diol or by a double condensation between a primary alkylamine and a 1,2-diol. At least one substituent is required on the piperazine ring to achieve the cyclization in good yield. The mechanism is believed to involve dehydrogenation of the 1,2-diol to the α-hydroxy aldehyde, which condenses with the amine to form the α-hydroxy imine. The latter rearranges to the corresponding α-amino carbonyl compound, which then reacts with another amine followed by reduction of the resulting imine. Piperazines are prepared by [Cp*IrCl 2]2-catalyzed heterocyclization of 1,2-diols with either 1,2-diamines or primary alkylamines. The reaction is performed in toluene or water and requires no stoichiometric additive. The key step in the mechanism is believed to be the isomerization of an α-hydroxy imine to the corresponding α-amino carbonyl compound. Copyright
