Check Digit Verification of cas no

The CAS Registry Mumber 133513-02-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,5,1 and 3 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 133513-02:
(8*1)+(7*3)+(6*3)+(5*5)+(4*1)+(3*3)+(2*0)+(1*2)=87
87 % 10 = 7
So 133513-02-7 is a valid CAS Registry Number.

Iodine-catalyzed one-pot synthesis of unsymmetrical meso-substituted porphyrins

Bo?ns, Benjamin,Faugeras, Pierre-Antoine,Vergnaud, Julien,Lucas, Romain,Teste, Karine,Zerrouki, Rachida

, p. 1994 - 1996 (2010)

The wide range use of 5-(4-nitrophenyl)-10,15,20-triphenylporphyrin is well established, but its synthesis requires two steps and is not very practical. This article describes an iodine-catalyzed one-pot synthesis of this unsymmetrical porphyrin that uses

Syntheses of Monosulfonated Phthalocyanines, Benzonaphthoporphyrazines and Porphyrins via the Meerwein Reaction

Kudrevich, Svetlana V.,Ali, Hasrat,Lier, Johan E.

, p. 2767 - 2774 (2007/10/02)

A variety of monosulfonated phthalocyanine, benzonaphthoporphyrazine and porphyrin derivatives have been prepared as single isomers in moderate to high yield using modified Meerwein reaction conditions.These amphiphilic dyes have a potential application as photosensitizers in the photodynamic therapy of cancer.
