Check Digit Verification of cas no

The CAS Registry Mumber 54247-36-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,2,4 and 7 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 54247-36:
(7*5)+(6*4)+(5*2)+(4*4)+(3*7)+(2*3)+(1*6)=118
118 % 10 = 8
So 54247-36-8 is a valid CAS Registry Number.

Direkte N-Arylierung von Amiden: Eine Verbesserung der Goldberg-Reaktion

Renger, Bernd

, p. 856 - 860 (2007/10/02)

The copper-catalyzed N-arylation of amides, the Goldberg reaction, usually requires drastic reaction conditions and produces only moderate yields of the desired products.Much better results can be achieved by modifying the reaction conditions.We used copper on silica as a catalyst and potassium acetate as a base and continuously removed the resulting acetic acid from the reaction mixture.In this way we gained high, in some cases nearly quantitative yields of the arylated or heteroarylated products.
