The CAS Registry Mumber 917824-20-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,7,8,2 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 917824-20:
(8*9)+(7*1)+(6*7)+(5*8)+(4*2)+(3*4)+(2*2)+(1*0)=185
185 % 10 = 5
So 917824-20-5 is a valid CAS Registry Number.

Synthesis of enantiomerically pure (+)- and (-)-protected 5-aminomethyl-1,3-oxazolidin-2-one derivatives from allylamine and carbon dioxide

Fernandez, Isabelle,Munoz, Luis

, p. 2548 - 2557 (2007/10/03)

The stereoselective synthesis of enantiomerically pure (5R)- and (5S)-aminomethyl-oxazolidinones with different protecting groups have been carried out from an allyl amine as the source of the carbon backbone. The key reaction is the high yield iodiocyclization of enantiomerically pure allylphenethyl amine in the presence of carbon dioxide.
