Check Digit Verification of cas no

The CAS Registry Mumber 1240314-99-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,0,3,1 and 4 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1240314-99:
(9*1)+(8*2)+(7*4)+(6*0)+(5*3)+(4*1)+(3*4)+(2*9)+(1*9)=111
111 % 10 = 1
So 1240314-99-1 is a valid CAS Registry Number.

Direct experimental evidence for the priority of flexible ligand skeleton in asymmetric friedel-crafts alkylation of indole with nitroalkenes

Liu, Han,Wang, Neng-Dong,Du, Da-Ming

experimental part, p. 114 - 120 (2010/08/20)

Direct experimental evidence for the priority of flexible ligand skeleton in asymmetric Friedel-Crafts alkylation was obtained through XRD analysis of flexible ligand/ZnCl2 complex, as well as synthesis of dihydroacridine-linked bis(oxazoline) ligands with planar rigid scaffold. A transition state model without NH φ interaction was proposed for the rigid ligands to interpret the inversion of absolute configuration.
