Check Digit Verification of cas no

The CAS Registry Mumber 209725-85-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,9,7,2 and 5 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 209725-85:
(8*2)+(7*0)+(6*9)+(5*7)+(4*2)+(3*5)+(2*8)+(1*5)=149
149 % 10 = 9
So 209725-85-9 is a valid CAS Registry Number.

Toward supramolecular ion channels formed by oligonucleotide analogs: Hydrophobic guanine dimers

Chen, Li,Sakai, Naomi,Moshiri, Sara T.,Matile, Stefan

, p. 3627 - 3630 (2007/10/03)

In this model study toward supramolecular channels formed by oligonucleotide analogs, we describe the synthesis of hydrophobic guanine dimers 1 - 4. We found that the solubility of guanine dimers 1 - 4 is significantly reduced compared to hydrophobic (iso)guanosine monomers and independent of the nature of substituents at the exocyclic amine. This indicates that the (deoxy)ribose is important to form soluble, ionophoric G- quartets.
