Check Digit Verification of cas no

The CAS Registry Mumber 50605-47-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,6,0 and 5 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 50605-47:
(7*5)+(6*0)+(5*6)+(4*0)+(3*5)+(2*4)+(1*7)=95
95 % 10 = 5
So 50605-47-5 is a valid CAS Registry Number.

Ditopic crown ether-guanidinium ion receptors for the molecular recognition of amino acids and small peptides

Sp?th, Andreas,K?nig, Burkhard

body text, p. 1859 - 1873 (2010/04/06)

A series of ditopic synthetic receptors based on a crown ether-guanidinium ion recognition motif is reported. The compounds show binding affinity to selected amino acids, including important neurotransmitters. The effect of the distance of the ammonium and the carboxylate ion, the rigidity of the spacer, and the use of pre-organized pyrrole- and pyrene-guanidinium groups on binding affinity and selectivity are discussed.

MONITORED AMINOLYSIS OF 3-ACYL-1,3-THIAZOLIDINE-2-THIONE WITH AMINO ACID AND ITS DERIVATIVE: PEPTIDE BOND FORMATION, CHEMOSELECTIVE ACYLATION, AND BRIDGING REACTION

Nagao, Yoshimitsu,Miyasaka, Tadayo,Seno, Kaoru,Yagi, Masahiro,Fujita, Eiichi

, p. 463 - 466 (2007/10/02)

As a new extention of the monitored aminolysis of 3-acyl-1,3-thiazolidine-2-thione, its applications to peptide bond formation, chemoselective acylation of amino acid, and bridging reaction on the enzyme model are reported.
