Check Digit Verification of cas no

The CAS Registry Mumber 344453-37-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,4,4,5 and 3 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 344453-37:
(8*3)+(7*4)+(6*4)+(5*4)+(4*5)+(3*3)+(2*3)+(1*7)=138
138 % 10 = 8
So 344453-37-8 is a valid CAS Registry Number.

Phototransformation of 4-nitrophenol using Pd phthalocyanines supported on single walled carbon nanotubes

Ogunbayo, Taofeek B.,Nyokong, Tebello

, p. 68 - 76 (2011)

Adsorption of palladium phthalocyanines complexes on single walled carbon nanotubes was carried out. The resulting composites were employed as catalysts for heterogeneous photocatalytic oxidation of 4-nitrophenol (4-NP) in aqueous media. Singlet oxygen was found to be involved in the phototransformation of 4-NP. Gas chromatographic separation gave hydroquinone and benzoquinone as the phototransformation products. Langmuir-Hinshelwood (L-H) model was employed to evaluate the adsorption and desorption equilibria of the reactants and the products. 2,3,9,10,16,17,23,24-octakis(dodecylthiophthalocyaninato) palladium(II) and 1,4,8,11,15,18,22,25-octakis(dodecylthio phthalocyaninato) palladium, containing the longest alkyl chain gave the best performances.
