Check Digit Verification of cas no

The CAS Registry Mumber 91668-63-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,6,6 and 8 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 91668-63:
(7*9)+(6*1)+(5*6)+(4*6)+(3*8)+(2*6)+(1*3)=162
162 % 10 = 2
So 91668-63-2 is a valid CAS Registry Number.

Organocatalytic Enantioselective Decarboxylative Protonation Reaction of Meldrum's Acid Derivatives under PTC Conditions

Legros, Fabien,Martzel, Thomas,Brière, Jean-Fran?ois,Oudeyer, Sylvain,Levacher, Vincent

, p. 1975 - 1983 (2018/05/15)

An original organocatalyzed enantioselective protonation sequence of a transient quaternary ammonium enolate species has been developed by starting from readily available disubstituted Meldrum's acid derivatives and phenols. Under phase-transfer-catalytic (PTC) conditions, chiral nonracemic 2-aryl propionic ester derivatives were obtained in good isolated yields with enantioselectivities up to 70 % ee. The usefulness of the approach was demonstrated by the synthesis of enantioenriched (S)-ibuprofen.
