Check Digit Verification of cas no
The CAS Registry Mumber 5399-63-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,9 and 9 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5399-63:
(6*5)+(5*3)+(4*9)+(3*9)+(2*6)+(1*3)=123
123 % 10 = 3
So 5399-63-3 is a valid CAS Registry Number.

Degradation of sodium 4-dodecylbenzenesulphonate photoinduced by Fe(III) in aqueous solution
Mailhot, Gilles,Asif, Ayaz,Bolte, Michele
, p. 363 - 370 (2000)
The Fe(III)-photoinduced degradation of 4-dodecylbenzenesulphonate (DBS) in aqueous solution was investigated. The mixing of DBS (1 mm) and Fe(III) (1 mm) solutions immediately led to the formation of a precipitate that contained DBS and monomeric Fe(OH)2+, the predominant Fe(III) species. Both species were also present in the supernatant. Irradiation of the supernatant solution resulted in a photoredox process that yielded Fe(II) and ·OH radicals. The disappearance of DBS was shown to involve only attack by ·OH radicals; the quantum yield of DBS disappearance is similar to the quantum yield of ·OH radical formation. A wavelength effect was also observed; the rate of DBS disappearance was higher for shorter wavelength irradiation. Five photoproducts, all containing the benzene sulphonate group, were identified. ·OH radicals preferentially abstract hydrogen from the carbon in the α position of the aromatic ring. The results show that the Fe(III)-photoinduced degradation of DBS could be used as an alternative method for polluted water treatment. (C) 2000 Elsevier Science Ltd.
