Check Digit Verification of cas no

The CAS Registry Mumber 171195-23-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,1,9 and 5 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 171195-23:
(8*1)+(7*7)+(6*1)+(5*1)+(4*9)+(3*5)+(2*2)+(1*3)=126
126 % 10 = 6
So 171195-23-6 is a valid CAS Registry Number.

Synthesis and characterization of amine adducts of tri(4-tolyl)boroxine and tri(3,5-xylyl)boroxine: molecular structure of (4-MeC6H4)3B2O3.cyclohexylamine

Beckett, Michael A.,Strickland, Gary C.,Varma, K. Sukumar,Hibbs, David E.,Hursthouse, Michael B.,Malik, K. M. Abdul

, p. 2623 - 2630 (2008/10/09)

19 1:1 adducts of the triarylboroxines (4-MeC6H4)3B3O3 (PTB) and (3,5-Me2C6H3)3B3O3 (MXB) with N-donor ligands (cyclohexylamine, 4-picoline, 3-picoline, piperidine, morpholine, isobutylamine, dimethylamine, isoquinoline and benzylamine) have been prepared by reaction of stoichiometric quantities of ligand and triarylboroxine in Et2O at room temperature. All 19 adducts have been characterized by elemental analysis, M pt, IR and (1)H and (13)C NMR. C6H11NH2.PTB has been characterized in the solid state by a single-crystal X-ray diffraction study. Solid-state (11)B MAS NMRresults for PTB and its adducts with cyclohexylamine and isoquinoline a re reported. In solution-variable temperature (1)H NMR of the morpholine, cyclohexylamine, isoquinoline and benzylamine adducts of PTB and MXB indicate that a ligand dissociation-recombination process is occuring with ΔG# of ca 43-49 kJ mol**-1.
