Check Digit Verification of cas no

The CAS Registry Mumber 3479-47-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,7 and 9 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3479-47:
(6*3)+(5*4)+(4*7)+(3*9)+(2*4)+(1*7)=108
108 % 10 = 8
So 3479-47-8 is a valid CAS Registry Number.

Tetrahydro-1,3-oxazin-6-ones as templates for the stereoselective synthesis of β-substituted L-aspartic acids

Burtin, Guillaume,Corringer, Pierre-Jean,Young, Douglas W.

, p. 3451 - 3459 (2007/10/03)

Protected (4S)-4-carboxytetrahydro-1,3-oxazin-6-ones have been synthesised either by Baeyer-Villiger reaction on a 4-ketoproline derivative or, more directly, from an aspartate derivative. Two strategies have been used to develop these compounds as chiral templates in the synthesis of β-substituted aspartic acids. In the first, formation of an enaminone using Bredereck's reagent, followed by reaction with a Grignard reagent gave a series of alkylidene derivatives which could be reduced from the less hindered side by heterogeneous catalytic hydrogenation to give cis-oxazinones in a completety stereoselective manner. Alternatively, an alkylation strategy, although trans-selective, gave mixtures of isomers. The oxazinones were converted to β-substituted aspartic acids and to regioselectively protected β-substituted aspartic acids without loss of stereochemistry ar either centre.

Cleavage of Esters under Nearly Neutral Conditions at High Pressure. Chemo- and Regioselective Hydrolysis in Organic Solvents

Yamamoto, Yoshinori,Furuta, Toshiaki,Matsuo, Jiro,Kurata, Tetsuro

, p. 5737 - 5738 (2007/10/02)

Hydrolysis of esters proceeded at room temperature under high pressure in the presence of iPr2NEt or N-methylmorpholine using CH3CN-H2O (60:1) as the solvent.This very mild procedure enables the smooth hydrolysis of biologically important compounds such as amino esters, aliphatic unsaturated fatty esters, and β-hydroxy esters; no racemization, no isomerization, and no side reactions take place.
