307494-00-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 307494-00-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,7,4,9 and 4 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 307494-00:
(8*3)+(7*0)+(6*7)+(5*4)+(4*9)+(3*4)+(2*0)+(1*0)=134
134 % 10 = 4
So 307494-00-4 is a valid CAS Registry Number.

Thalidomide metabolites and analogs. Part 2: Cyclic derivatives of 2-N-phthalimido-2S,3S (3-hydroxy) ornithine

Luzzio,Thomas,Figg

, p. 7151 - 7155 (2000)

E-(5-N-phthaloyl)-2-pentenoic acid benzyl ester was dihydroxylated by a Sharpless AD-mix protocol followed by mononosylation of the resultant 2R,3S diol. Azide displacement of the mononosylate followed by protection with the TBDMS group gave the ε-N-phthaloyl-substituted-β-tert-butyldimethylsilyloxy-α-azidocarboxylic acid benzylester. Hydrazinolysis resulted in removal of the phthalimide group with concomitant lactamization to the 4-silyloxy-3-azidopiperidinones. Staudinger reduction of the azidopiperidinones followed by N-phthaloylation and hydrolysis of the silyl group afforded the 4'-hydroxylated-6'-deoxythalidomide derivatives.
