Check Digit Verification of cas no
The CAS Registry Mumber 150884-73-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,0,8,8 and 4 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 150884-73:
(8*1)+(7*5)+(6*0)+(5*8)+(4*8)+(3*4)+(2*7)+(1*3)=144
144 % 10 = 4
So 150884-73-4 is a valid CAS Registry Number.

Diastereofacial Selectivity in Reduction of Chiral Tetramic Acids
Galeotti, Nathalie,Poncet, Joeel,Chiche, Laurent,Jouin, Patrick
, p. 5370 - 5376 (2007/10/02)
The reduction of (5S)-5-alkyl-2,4-dioxopyrrolidines, so-called tetramic acids, by NaBH4 gives only partial diastereofacial selectivity in the case of the N-substituted analogues 9f-i, unlike the carbamate derivatives 9a-e which give the reduced cis-pyrrolidinones 10βa-e.Increasing the steric hindrance of either the N- or C-5-substituents enhances the re-face selectivity.On the other hand, reduction of the heterobicyclic compound 9n leads to a dramatic reversal of the stereoselectivity.Preliminary calculations show that the N-atom of the ring is slightlypyramidalized; the direction of hydride addition could be a consequence of this finding.
