142397-44-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 142397-44-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,3,9 and 7 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 142397-44:
(8*1)+(7*4)+(6*2)+(5*3)+(4*9)+(3*7)+(2*4)+(1*4)=132
132 % 10 = 2
So 142397-44-2 is a valid CAS Registry Number.

Photoinduced Electron Transfer in Porphyrin-Quinone Cyclophanes, 5. - Quinone-Porphyrin-Quinone and Quinone-Porphyrin-Donor Cyclophanes: Syntheses, Structures and Electron-Transfer-Related Properties

Staab, Heinz A.,Weiser, Juergen,Baumann, Ernst

, p. 2275 - 2284 (2007/10/02)

To study the structure dependence of photoinduced electron transfer between porphyrins and quinones the concept of a new family of porphyrin-quinone cyclophanes with vertical arrangements of porphyrin and quinone units is presented.The syntheses of the quinone-porphyrin-quinone cyclophane 1, the prototype of this series, and of the quinone-porphyrin-donor cyclophanes 12 and 14 are described.Spectroscopic data are discussed with regard to the structures involved and in relation to electron-transfer reactions occurring in these systems. Key Words: Photosynthesis models / Photoinduced electron transfer / Porphyrin-quinone cyclophanes
