Check Digit Verification of cas no

The CAS Registry Mumber 664326-19-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,4,3,2 and 6 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 664326-19:
(8*6)+(7*6)+(6*4)+(5*3)+(4*2)+(3*6)+(2*1)+(1*9)=166
166 % 10 = 6
So 664326-19-6 is a valid CAS Registry Number.

Metalloporphyrin receptors for histidine-containing peptides

Liu, Hui,Li, Zhan-Ting

, p. 659 - 662 (2014/06/09)

Two new ditopic metalloporphyrin receptors constructed by combining metalloporphyrin with crown ethers have been prepared and characterized. 1H NMR and MS spectra confirmed the complexation of receptor with peptide driven by coordination interaction and hydrogen bonding. UV/vis experiments revealed that the receptors exhibited high binding affinity to histidine-containing peptides. These receptors could differentiate short peptides of C-terminal histidine and N-terminal histidine and formed the most stable complexes with tripeptide.
