132249-34-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 132249-34-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,2,4 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 132249-34:
(8*1)+(7*3)+(6*2)+(5*2)+(4*4)+(3*9)+(2*3)+(1*4)=104
104 % 10 = 4
So 132249-34-4 is a valid CAS Registry Number.

Straightforward method for the synthesis of selenocysteine and selenocystine derivatives from L-serine methyl ester

Braga, Antonio L.,Wessjohann, Ludger A.,Taube, Paulo S.,Galetto, Fabio Z.,De Andrade, Fabiano M.

supporting information; experimental part, p. 3131 - 3137 (2010/11/02)

A set of selenoamino acids has been efficiently synthesized under smooth conditions by a simple, flexible and modular strategy. In this method, O-mesylated l-serine methyl ester is generated in situ and directly substituted with various selenolate anions

A short synthetic approach to chiral serine azido derivatives

Panda, Gautam,Rao, N. Venugopal

, p. 714 - 716 (2007/10/03)

We report a new synthetic methodology for the synthesis of chiral serine azido derivatives through a conversion of N-protected (Boc, Cbz and Fmoc) serine amino acid into its corresponding Weinreb amide. Thus, acidity of the α-proton of the serine is reduced and it allows nucleophilic addition reaction onto Weinreb amide to furnish chiral serine azido derivatives.

A total synthesis of (-)-slaframine from (+)-cis-(2R,3S)-3-hydroxyproline

Knight,Sibley

, p. 6607 - 6610 (2007/10/02)

A total synthesis of the naturally occurring indolizidine (-)-Slaframine 4 has been achieved, starting from the cis-3-hydroxyproline derivative 1, in which a key step is a Julia olefination reaction using the dianion derived from the β-aminosulfone 5.
