Check Digit Verification of cas no

The CAS Registry Mumber 15131-31-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,1,3 and 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 15131-31:
(7*1)+(6*5)+(5*1)+(4*3)+(3*1)+(2*3)+(1*1)=64
64 % 10 = 4
So 15131-31-4 is a valid CAS Registry Number.

Ruthenate(VI)-catalysed dehydrogenation of primary amines to nitriles, and crystal structures of cis-2*0.5MeOH and cis-2*CH2Cl2

Griffith, William P.,Reddy, Bharti,Shoair, Abdel G. F.,Suriaatmaja, Maria,White, Andrew J. P.,Williams, David J.

, p. 2819 - 2826 (2007/10/03)

Catalytic dehydrogenation of benzylic and other primary amines RCH2NH2 to the corresponding nitriles RCN by the system trans-2-/S2O82- has been investigated.The complex cis-2+ and the new cis-2+ (R = o-, m- or p-ClC6H4, o-MeC6H4, o- or p-MeOC6H4); cis-2+ (R = Ph or p-MeOC6H4) and cis-2+ have been made, and dehydrogenation of the co-ordinated amine in the ruthenium complexes to the corresponding nitriles in cis-2+ (L-L = bipy or phen) by peroxodisulfate demonstrated.The crystal structures of cis-*0.5MeOH and cis-2*CH2Cl2, the latter a product of co-ordinated amine dehydrogenation by peroxodisulfate to give cis-2+, were determined.Raman, infrared and 1H NMR data for the complexes have been measured; the latter suggest that the cis configurations of the amine complexes are retained in solution.
