Check Digit Verification of cas no

The CAS Registry Mumber 1234856-62-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,4,8,5 and 6 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1234856-62:
(9*1)+(8*2)+(7*3)+(6*4)+(5*8)+(4*5)+(3*6)+(2*6)+(1*2)=162
162 % 10 = 2
So 1234856-62-2 is a valid CAS Registry Number.

Development of diphenylamine-linked bis(imidazoline) ligands and their application in asymmetric Friedel-Crafts alkylation of indole derivatives with nitroalkenes

Liu, Han,Du, Da-Ming

, p. 1113 - 1118 (2010)

The new diphenylamine-linked bis(imidazoline) ligands were prepared through Kelly-You's imidazoline formation procedure mediated by Hendrickson 's reagent in good yields. The novel ligands were tested in the asymmetric Friedel-Crafts alkylation of indole derivatives with nitroalkenes. In most cases, good yields (up to 97%) and excellent enantioselectivities (up to 98%) can be achieved. The optimized bis(imidazoline) ligand with trans-diphenyl substitution on the imidazoline ring gave better enantioselectivity than the corresponding bis(oxazoline) ligand.
