Check Digit Verification of cas no
The CAS Registry Mumber 182212-33-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,2,2,1 and 2 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 182212-33:
(8*1)+(7*8)+(6*2)+(5*2)+(4*1)+(3*2)+(2*3)+(1*3)=105
105 % 10 = 5
So 182212-33-5 is a valid CAS Registry Number.

Synthesis, resolution and crystal structure of a new optically active nitroxide radical
Benfaremo, Nicholas,Steenbock, Marco,Klapper, Markus,Muellen, Klaus,Enkelmann, Volker,Cabrera, Karin
, p. 1413 - 1415 (2007/10/03)
The synthesis of the readily available racemate of the nitroxide radical 5 is described. The product exhibits exclusively the irons configuration. The cis product was not obtained. Optically pure enantiomers of 5 were isolated in gram quantities by chiral HPLC. Thus, separation of the enantiomers of a nitroxide radical was achieved for the first time. The structure of 5 was proven by a single-crystal diffraction study. VCH Verlagsgesellschaft mbH, 1996.
