701980-20-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 701980-20-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,0,1,9,8 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 701980-20:
(8*7)+(7*0)+(6*1)+(5*9)+(4*8)+(3*0)+(2*2)+(1*0)=143
143 % 10 = 3
So 701980-20-3 is a valid CAS Registry Number.

Phenanthridinium as an artificial base and charge donor in DNA
Amann, Nicole,Huber, Robert,Wagenknecht, Hans-Achim
, p. 1845 - 1847 (2007/10/03)
A tool for time-resolved studies: The phenanthridinium unit of ethidium was incorporated into oligonucleotides (see scheme) as an artificial DNA base. The resulting duplexes can be used to study electron-transfer processes by spectroscopic techniques and
