130727-56-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130727-56-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,7,2 and 7 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 130727-56:
(8*1)+(7*3)+(6*0)+(5*7)+(4*2)+(3*7)+(2*5)+(1*6)=109
109 % 10 = 9
So 130727-56-9 is a valid CAS Registry Number.

How far can a carbanion delocalize? 13C NMR studies on soliton model compounds
Tolbert, Laren M.,Ogle, Mark E.

For well-defined π systems, 13C chemical shifts are correlated with π-electron density. We have used this correlation to develop models for charge carriers in n-doped polyacetylene ("solitons") that allow us to determine if the charge density d
