Check Digit Verification of cas no

The CAS Registry Mumber 138692-79-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,6,9 and 2 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 138692-79:
(8*1)+(7*3)+(6*8)+(5*6)+(4*9)+(3*2)+(2*7)+(1*9)=172
172 % 10 = 2
So 138692-79-2 is a valid CAS Registry Number.

Synthesis and Fluorescence Properties of Selectively Metallated Diporphyrins with Electron-Accepting Moieties

Nagata, Toshi

, p. 3005 - 3016 (2007/10/02)

Synthesis of selectively metallated diporphyrins with electron-accepting moieties is described.Steady-state fluorescence spectra of these compounds showed substantial quenching of the fluorescence of the free-base porphyrin.A possible "superexchange" mechanism of long-range electron transfer is discussed.
