Check Digit Verification of cas no

The CAS Registry Mumber 33934-09-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,9,3 and 4 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 33934-09:
(7*3)+(6*3)+(5*9)+(4*3)+(3*4)+(2*0)+(1*9)=117
117 % 10 = 7
So 33934-09-7 is a valid CAS Registry Number.

Organocatalyzed synthesis of isoxazolidin-5-ones: The meldrum's acid approach

Postikova, Svetlana,Tite, Tony,Levacher, Vincent,Briere, Jean-Francois

, p. 2513 - 2517 (2013)

Meldrum's acid has turned out to be a useful ketene equivalent when faced to nitrone dipoles to form various isoxazolidin-5-one derivatives under very mild Bronsted base organocatalytic conditions. The first asymmetric version of this original domino anionic formal [3+2] cycloaddition- decarboxylation reaction was demonstrated by means of quinine-based organocatalysts. Copyright
