Check Digit Verification of cas no
The CAS Registry Mumber 5257-20-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,5 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5257-20:
(6*5)+(5*2)+(4*5)+(3*7)+(2*2)+(1*0)=85
85 % 10 = 5
So 5257-20-5 is a valid CAS Registry Number.

Binding and Transport of Alkali and Alkaline Earth Metal Ions by Synthetic Macrolides Containing Tetrahydropyran Rings
Tajima, Ichiro,Okada, Masahiko,Sumitomo, Hiroshi
, p. 4096 - 4100 (2007/10/02)
Ion binding and transport abilities of 10-, 20-, and 25-membered macrolides (2, 4, and 5, respectively) consisting of alternating tetrahydropyran and ester moieties were evaluated mainly by extraction equilibrium and transport experiments of various metal picrates.The macrolide 2 was totally ineffective in ion binding and transport.The ion extraction constants of the macrotetrolide 4 and the macropentalide 5 were found to be in the order of ca. 10-102, and their ion selectivity sequences were Cs+ > Rb+ > K+ > Na+ > Li+ and Ba2+ > Ca2+.The transport rate of metal picrates mediated by 4 and 5 through organic liquid membranes decreased in the order, Cs+ > Rb+ > K+ > Ba2+ > Ca2+ ca.Na+ > Li+, the selectivity of K+ over Na+ being ca. 2-3.Separated measurements of ion uptake and ion release, along with the selectivity sequences above, suggested that the ion uptake step was rate determining in the transport of metal picrates by 4 and 5.These ion binding properties and transport behaviors are discussed in comparison with those of some natural and synthetic ionophores.
