Check Digit Verification of cas no
The CAS Registry Mumber 77291-90-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,2,9 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 77291-90:
(7*7)+(6*7)+(5*2)+(4*9)+(3*1)+(2*9)+(1*0)=158
158 % 10 = 8
So 77291-90-8 is a valid CAS Registry Number.

Enantioselective preparation of 2,4-disubstituted azetidines
Marinetti, Angela,Hubert, Philippe,Genêt, Jean-Pierre
, p. 1815 - 1820 (2007/10/03)
Chiral C2-symmetric N-benzylazetidines have been conveniently prepared from optically pure anti-1,3-diols without loss of enantiomeric purity. N- Debenzylation led to the corresponding N-unsubstituted azetidines, which were then subjected to palladium-catalysed coupling reactions with aryl bromides to afford chiral N-arylazetidines. (R,R)-N-Benzyl-2,4-dimethylazetidine has been employed in the synthesis of a new cyclopalladated complex, which can be used, for instance, as a chiral recognition agent for phosphorus ligands.
Chiral 1,2-bis(phosphetano)benzenes: Preparation and use in the Ru- catalyzed hydrogenations of carbonyl derivatives
Marinetti, Angela,Genet, Jean-Pierre,Jus, Sebastien,Blanc, Delphine,Ratovelomanana-Vidal, Virginie
, p. 1160 - 1165 (2007/10/03)
Chiral 1,2-bis(phosphetano)benzenes are readily prepared from accessible, optically pure 1,3-diol cyclic sulfates. Their ruthenium complexes catalyze the enantioselective hydrogenations of functionalized carbonyls with moderate-to-high enantiomeric excesses. High levels of diastereo- and enantioselectivity are achieved, especially in the hydrogenation of β-diketones to the corresponding anti-1,3-diols.
