Check Digit Verification of cas no

The CAS Registry Mumber 215935-55-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,5,9,3 and 5 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 215935-55:
(8*2)+(7*1)+(6*5)+(5*9)+(4*3)+(3*5)+(2*5)+(1*5)=140
140 % 10 = 0
So 215935-55-0 is a valid CAS Registry Number.

Novel covalently linked porphyrin dimers for controlled intramolecular energy transfer

Sen, Avijit,Krishnan

, p. 499 - 506 (1998)

Dimers constituting differing porphyrin basicities undergo selective demetallation or protonation of one unit of the dimer. The efficiency of singlet excited energy transfer from neutral free-base/zinc(II) porphyrin to diprotonated porphyrin unit could be
