Check Digit Verification of cas no

The CAS Registry Mumber 139305-99-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,3,0 and 5 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 139305-99:
(8*1)+(7*3)+(6*9)+(5*3)+(4*0)+(3*5)+(2*9)+(1*9)=140
140 % 10 = 0
So 139305-99-0 is a valid CAS Registry Number.

Chiroptical Probing of Lanthanide-Directed Self-Assembly Formation Using btp Ligands Formed in One-Pot Diazo-Transfer/Deprotection Click Reaction from Chiral Amines

Byrne, Joseph P.,Martínez-Calvo, Miguel,Peacock, Robert D.,Gunnlaugsson, Thorfinnur

, p. 486 - 490 (2016)

A series of enantiomeric 2,6-bis(1,2,3-triazol-4-yl)pyridines (btp)-containing ligands was synthesized by a one-pot two-step copper-catalyzed amine/alkyne click reaction. The EuIII- and TbIII-directed self-assembly formation of these ligands was studied in CH3CN by monitoring their various photophysical properties, including their emerging circular dichroism and circularly polarized luminescence. The global analysis of the former enabled the determination of both the stoichiometry and the stability constants of the various chiral supramolecular species in solution.
