Check Digit Verification of cas no

The CAS Registry Mumber 312311-67-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,2,3,1 and 1 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 312311-67:
(8*3)+(7*1)+(6*2)+(5*3)+(4*1)+(3*1)+(2*6)+(1*7)=84
84 % 10 = 4
So 312311-67-4 is a valid CAS Registry Number.

β3-Amino acids by nucleophilic ring-opening of N-nosyl aziridines

Farràs, Jaume,Ginesta, Xavier,Sutton, Peter W,Taltavull, Joan,Egeler, Frank,Romea, Pedro,Urpí, Fèlix,Vilarrasa, Jaume

, p. 7665 - 7674 (2007/10/03)

N-Nosyl aziridines can be easily prepared from 1,2-amino alcohols derived from α-amino acids. Nucleophilic ring-opening of N-nosyl aziridines with cyanide ions followed by hydrolysis of the corresponding nitriles lead to N-nosyl β3-amino acids, which can be readily converted into a variety of derivatives bearing adequate functionality for peptide synthesis. The proposed methodology is simple, efficient, and amenable to large-scale preparations.

Pseudoaxially disubstituted cyclo-β3-tetrapeptide scaffolds

Sutton, Peter W.,Bradley, Adrian,Farràs, Jaume,Romea, Pedro,Urpí, Fèlix,Vilarrasa, Jaume

, p. 7947 - 7958 (2007/10/03)

An N,N-disubstituted cyclo-β3-tetrapeptide, identified as a potential molecular scaffold, has been synthesised on a multigram scale from β-homophenylalanine by employing a nosylate-based protection strategy. C2-Symmetric derivatives containing pseudoaxial, combinatorially addressable functionalities have been prepared from the parent cyclopeptide. (C) 2000 Elsevier Science Ltd.
