Check Digit Verification of cas no

The CAS Registry Mumber 241495-72-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,1,4,9 and 5 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 241495-72:
(8*2)+(7*4)+(6*1)+(5*4)+(4*9)+(3*5)+(2*7)+(1*2)=137
137 % 10 = 7
So 241495-72-7 is a valid CAS Registry Number.

Novel cryptand analogs incorporating a chiral spiran moiety

Garcia, Christophe,Pointud, Yvon,Jeminet, Georges,Dugat, Denise

, p. 4993 - 4996 (2007/10/03)

Macrobicyclic polyethers based on the cryptand model displaying a chirality due to a spiran junction were synthesized from diamines 7 and 8. Results of attempted direct macrobicyclisation varied with the length the αω-oligoethyleneglycol ditosylates chain used as reagent. The expected structure was obtained only for triethyleneglycol ditosylate. The complexing properties of the diaza-octaoxa ligand 11, with alkaline and ammonium cations, were measured in THF by UV-Visible spectrophotometry.
