Check Digit Verification of cas no

The CAS Registry Mumber 1164334-53-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,4,3,3 and 4 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1164334-53:
(9*1)+(8*1)+(7*6)+(6*4)+(5*3)+(4*3)+(3*4)+(2*5)+(1*3)=135
135 % 10 = 5
So 1164334-53-5 is a valid CAS Registry Number.

IBiox[(-)-menthyl]: A sterically demanding chiral NHC ligand

Wuertz, Sebastian,Lohre, Claudia,Froehlich, Roland,Bergander, Klaus,Glorius, Frank

supporting information; experimental part, p. 8344 - 8345 (2009/10/24)

(Figure Presented) An exceedingly sterically demanding, rigid, and chiral NHC ligand, IBiox[(-)-menthyl] (1), was prepared and structurally characterized. With a buried volume of 50percent, this ligand arguably represents one of the most sterically demanding monodentate ligands. The ability to use aryl chloride substrates in intramolecular palladium-catalyzed ,-arylations reveals its unique reactivity. Moreover, C2-symmetric 1 allows the highly enantioselective formation of oxindoles withup to 99percent ee.
