Check Digit Verification of cas no

The CAS Registry Mumber 139747-91-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,7,4 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 139747-91:
(8*1)+(7*3)+(6*9)+(5*7)+(4*4)+(3*7)+(2*9)+(1*1)=174
174 % 10 = 4
So 139747-91-4 is a valid CAS Registry Number.

Photoinduced Intramolecular Electron Transfer in Viologen-Linked Zinc Porphyrins in Dimethylsulfoxide

Okura, Ichiro,Hosono, Hideyuki

, p. 4466 - 4469 (1992)

Compounds containing a viologen linked to a zinc porphyrin via methylene groups have been synthesized, and photoinduced intramolecular electron transfer between porphyrin and viologen was observed.The photoexcited singlet state of the porphyrin was quenched by the bonded viologen, the photoexcited triplet state was quenched, and the lifetime of the charge separated species was about 1 μs.
