Check Digit Verification of cas no
The CAS Registry Mumber 89-02-1 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 9 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 89-02:
(4*8)+(3*9)+(2*0)+(1*2)=61
61 % 10 = 1
So 89-02-1 is a valid CAS Registry Number.

Nucleophilic Aromatic Substitution. Part XV. Phase-Transfer Catalysis of Sulfodechlorination and Identification of a Primary Product of Sulfite Ion with 1-Chloro-2,4-dinitrobenzene

With conventional phase-transfer catalysis using quaternary ammonium salts, yields of 2,4-dinitrobenzenesulfonic acid (2) in the sulfodechlorination of 1-chloro-2,4-dinitrobenzene (1) with sulfite ions are no better than those obtained with the classical method in aqueous ethanol (80-82percent).Yields up to 97percent and a very pure product are obtained, however, by using protonated tertiary amines as catalysts.The optimum chain-lenght of the amine is found with tributylamine.On mixing solutions of the reagents and catalysts a strong bluish-red colour develops immediately, but dis appears within ca. 1 h.Comparison of the NMR. spectrum of this primary product with model adducts of sulfite ions and di- and trinitrobenzene derivatives demonstrates that the primary addition of the nucleophile to 1-chloro-2,4-dinitrobenzene does not take place at C(1), but at C(5).It is shown that the increments calculated for a C(sp3)-SO3- group and for the 1,3-dinitro- and 1,3,5-trinitropentadienyl ring moieties can be employed for the approximate calculation of 1H-chemical shifts using Clerc and Pretschs's modification of the Shoolery rules.
SYNTHESIS OF TETRAPHENYLSTIBONIUM ALKYL- AND ARYLSULPHONATES. CRYSTAL STRUCTURE OF TETRAPHENYLSTIBONIUM BENZENESULPHONATE HYDRATE

, p. 21 - 28 (2007/10/02)
The tetraphenylstilbonium sulphonates Ph4SbO3SR*nH2O (n = 1, R = C6H5; n = 0, R = CH3, CF3, CH2CH2OH, 4-CH3C6H4, 2,4-(NO2)2C6H3) have been obtained by neutralization of tetraphenylstibonium hydroxide with the appropriate alkyl- or aryl-sulphonic acid.The crystal structure of tetraphenylstibonium benzenesulfonate hydrate has been determined by single crystal X-ray diffraction.The sulphonate group is unidentately coordinated to antimony, which has a distorted trigonal bipyramidal environment.The rather long Sb-O bond, (2.506(4) Angstroem) and the distortion of the polyhedron around Sb, and the IR data for the sulphonate group are consistent with the assumption of a large ionic bond character in the Sb-O bond.From IR data analogous molecular structures are inferred for the other tetraphenylstibonium sulphonates.
