Check Digit Verification of cas no

The CAS Registry Mumber 223717-80-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,3,7,1 and 7 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 223717-80:
(8*2)+(7*2)+(6*3)+(5*7)+(4*1)+(3*7)+(2*8)+(1*0)=124
124 % 10 = 4
So 223717-80-4 is a valid CAS Registry Number.

Synthesis and characterisation of some new N-glycosides containing substituted pyridopyrimidinone, pyrimidopyridazinone, thiazolopyrimidinone and quinolizin-4-one moiety

Simunek, Petr,Svete, Jurij,Stanovnik, Branko

, p. 2477 - 2491 (2011/04/17)

A series of new N-glycosides (D-glucosides, D-mannosides, L-and D-arabinosides, D-xylosides and one D-galactoside) containing heterocyclic moiety have been prepared by reaction of the corresponding heterocyclic amines with pyranoses in boiling methanol. The structures of the prepared compounds have been studied by means of proton and carbon NMR spectroscopy. In the most cases the products existed in DMSO solution as the single anomers.
