Check Digit Verification of cas no

The CAS Registry Mumber 1192371-33-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,2,3,7 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1192371-33:
(9*1)+(8*1)+(7*9)+(6*2)+(5*3)+(4*7)+(3*1)+(2*3)+(1*3)=147
147 % 10 = 7
So 1192371-33-7 is a valid CAS Registry Number.

Expanded ring and functionalised expanded ring N-heterocyclic carbenes as ligands in catalysis

Binobaid, Abeer,Iglesias, Manuel,Beetstra, Dirk J.,Kariuki, Benson,Dervisi, Athanasia,Fallis, Ian A.,Cavell, Kingsley J.

experimental part, p. 7099 - 7112 (2010/02/15)

The synthesis of new functionalised 6- and 7-membered NHC (N-heterocyclic carbene) precursors bearing anisidyl or pyridine N-substituents, both symmetrically and non-symmetrically substituted is reported. Their corresponding rhodium(i) and iridium(i) complexes, M(COD)(NHC)Cl, were also prepared and characterised. The unusual Rh(iii)/Rh(i) salt, [Rh(η2-NHC-py) 2Cl2][Rh(COD)Cl2], was obtained with one of the pyridyl-functionalised NHC ligands. Single-crystal X-ray analyses have been obtained for the majority of the complexes and NHC salts. The activity of these complexes was tested in the hydrogenation of a range of substrates with molecular hydrogen, including 1-cyclooctadiene and 2-methyl styrene, where they show enhanced activity and stability in comparison to non-functionalised NHC analogues, operating under exceptionally mild conditions (ambient temperature and atmospheric pressure).
