Check Digit Verification of cas no
The CAS Registry Mumber 215297-21-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,5,2,9 and 7 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 215297-21:
(8*2)+(7*1)+(6*5)+(5*2)+(4*9)+(3*7)+(2*2)+(1*1)=125
125 % 10 = 5
So 215297-21-5 is a valid CAS Registry Number.

Effect of preorganization on the affinity of synthetic DNA binding motifs for nucleotide ligands
Vollmer,Richert
, p. 5734 - 5742 (2015)
Triplexes with a gap in the purine strand have been shown to bind adenosine or guanosine derivatives through a combination of Watson-Crick and Hoogsteen base pairing. Rigidifying the binding site should be advantageous for affinity. Here we report that cl
