Check Digit Verification of cas no

The CAS Registry Mumber 321426-45-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,1,4,2 and 6 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 321426-45:
(8*3)+(7*2)+(6*1)+(5*4)+(4*2)+(3*6)+(2*4)+(1*5)=103
103 % 10 = 3
So 321426-45-3 is a valid CAS Registry Number.

Polythiazole linkers as functional rigid connectors: A new RGD cyclopeptide with enhanced integrin selectivity

Ruiz-Rodriguez,Miguel,Preciado,Acosta,Adan,Bidon-Chanal,Luque,Mitjans,Lavilla,Albericio

, p. 3929 - 3935 (2014)

Polythiazole amino acids clasp linear peptides to generate cyclic derivatives, however, the resulting species are not merely stapled peptides but bear a complex heterocyclic moiety displaying its intrinsic set of interactions. As a proof of concept, a bisthiazole moiety has been grafted onto an RGD sequence to deliver a new cilengitide analogue with improved integrin selectivity and remarkable in vivo antiangiogenic activity.
