Check Digit Verification of cas no

The CAS Registry Mumber 1243833-21-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,3,8,3 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1243833-21:
(9*1)+(8*2)+(7*4)+(6*3)+(5*8)+(4*3)+(3*3)+(2*2)+(1*1)=137
137 % 10 = 7
So 1243833-21-7 is a valid CAS Registry Number.

Ligand-free palladium-catalyzed facile construction of tetra cyclic dibenzo[b,h][1,6]naphthyridine derivatives: Domino sequence of intramolecular C-H bond arylation and oxidation reactions

Singh, Jay Bahadur,Chandra Bharadwaj, Kishor,Gupta, Tanu,Singh, Radhey M.

, p. 26993 - 26999 (2016/03/25)

A ligand-free Pd-catalyzed approach has been developed for the synthesis of dibenzo-fused naphthyridines. The reaction involves a one-pot domino sequence of reactions involving C-H functionalisation and oxidation. The reaction was applicable to a wide range of substrates, giving the required product. Further fluorescence studies were performed where the Stoke's shift was found to be dependent on the polarity of the solvent.
