Check Digit Verification of cas no

The CAS Registry Mumber 28995-74-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,9,9 and 5 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 28995-74:
(7*2)+(6*8)+(5*9)+(4*9)+(3*5)+(2*7)+(1*4)=176
176 % 10 = 6
So 28995-74-6 is a valid CAS Registry Number.

An improved synthesis of vinyl- and β-iodovinyl sulfones by a molecular iodine-mediated one-pot iodosulfonationdehydroiodination reaction

An improved one-pot method to synthesize vinyl sulfones from unsaturated systems by using molecular iodine/sodium arenesulfinate/sodium acetate as reagents was described. Vinyl sulfones derived from styrene derivatives were generally obtained in good to excellent yields except for those bearing strong electron releasing substituent. Aliphatic alkenes and activated alkenes gave the corresponding vinyl sulfone products in moderate to good yields. Arylacetylenes yielded the respective β-iodovinyl sulfones in good yields while low yield was observed with aliphatic terminal alkyne. The potentials of the method entail simplicity, short reaction time, non-anhydrous reaction conditions, employing inexpensive, non-metallic reagent and integrating two reactions that are commonly accomplished separately into a single operation.

Addition of Arenesulphonyl Iodides to Substituted Phenylacetylenes

Silva Correa, Carlos M. M. da,Fleming, Maria Daniela C. M.

, p. 103 - 108 (2007/10/02)

The products of the addition of toluene-p-sulphonyl iodide to substituted phenylacetylenes (and styrenes) are studied.The regiospecificity and stereoselectivity of trans addition to acetylenes is inferred from (1)H n.m.r. spectroscopy.The effect of substituents on the reactivity of substituted phenylacetylenes towards substituted beenzenesulphonyl radicals generated by photolysis of sulphonyl iodides is studied.Phenylacetylenes with electron-donating substituents react faster.Relative reactivities yield good Hammet-Brown correlations showing the electrophilic character of sulphonyl radicals towards phenylacetylenes.The selectivity of the addition (measured by ρ) of different sulphonyl radicals towards the same set of acetylenes ranges from -0.53 to -0.93 and shows a tendency to be smaller for benzenesulphonyl iodides carrying electron donating substituents.Results are discussed in terms of polar effects on the transition state and frontier molecular orbital theory.
