Check Digit Verification of cas no

The CAS Registry Mumber 1046478-47-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,6,4,7 and 8 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1046478-47:
(9*1)+(8*0)+(7*4)+(6*6)+(5*4)+(4*7)+(3*8)+(2*4)+(1*7)=160
160 % 10 = 0
So 1046478-47-0 is a valid CAS Registry Number.

Pd-catalyzed cross-coupling reactions with carbonyls: Application in a very efficient synthesis of 4-aryltetrahydropyridines

Barluenga, Jose,Tomas-Gamasa, Maria,Moriel, Patricia,Aznar, Fernando,Valdes, Carlos

supporting information; experimental part, p. 4792 - 4795 (2009/05/07)

A method is proposed to prepare 4-aryltetrahydropyridines by a Pd-catalyzed cross-coupling reaction by using tosylhydrazone as the nucleophilic coupling agent without stoichiometric organometallic reagent. Palladium-catalyzed couplings can be used for the formation of C-C linkages. It was observed during study that tosylhydrazone can be generated by employing 4-piperidones directly in the cross-coupling reaction with tetrahydropyridines in very high yields. It was also found during study that the ketones and aldehydes can be employed as nucleophilic coupling partners in a reaction without using stoichiometric organometallic reagent. The study concluded that the method can be used to prepare different types of di- and trisubstituted olefins at large scale.
