1099828-11-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1099828-11-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,9,9,8,2 and 8 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1099828-11:
(9*1)+(8*0)+(7*9)+(6*9)+(5*8)+(4*2)+(3*8)+(2*1)+(1*1)=201
201 % 10 = 1
So 1099828-11-1 is a valid CAS Registry Number.

A flexible route to chiral 2-endo-substituted 9-oxabispidines and their application in the enantioselective oxidation of secondary alcohols

Breuning, Matthias,Steiner, Melanie,Mehler, Christian,Paasche, Alexander,Hein, David

supporting information; experimental part, p. 1407 - 1410 (2009/07/11)

A new and flexible route to enantiomerically pure bi-and tricyclic 9-oxabispidines has been developed with use of (1R,5S)-7-methyl-2-oxo-9-oxa-3,7- diazabicyclo[33.1]nonane-3-carboxylic acid tert-butyl ester as the common late-stage intermediate. The 9-oxabispidines synthesized were evaluated as the chiral ligands in the Pd(II)-catalyzed oxidative kinetic resolution of secondary alcohols giving good to excellent selectivity factors of up to 19.
