Check Digit Verification of cas no

The CAS Registry Mumber 77083-42-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,0,8 and 3 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 77083-42:
(7*7)+(6*7)+(5*0)+(4*8)+(3*3)+(2*4)+(1*2)=142
142 % 10 = 2
So 77083-42-2 is a valid CAS Registry Number.

The reaction of sulfenate esters with acyl chlorides. Formation of sulfenyl chlorides, and trapping thereof with alkenes

Brown, Charles,Evans, Graham R.

, p. 679 - 682 (1996)

The reaction of aryl sulfenate esters with acyl chlorides is described: the formation of sulfenyl chlorides and carboxylic esters occurs, and the reactive sulfenyl chlorides are trapped with cyclohexene as the β-chloro-sulfides.

Elimination and Addition Reactions. Part 37. A Comparative Study of Electronic, Steric , and Solvent Effects upon Reactivity in Additions of Benzenesulphenyl Chloride to Alkenes

Jones, G. Alun,Stirling, Charles J. M.,Bromby, Norman G.

, p. 385 - 394 (2007/10/02)

Rates of additions of benzenesulphenyl chloride to 35 alkenes in several solvents have been measured, and the products of the reactions have in most cases been identified.Results for arylalkenes broadly confirm previous work, but the responses to solvent change are not uniform throughout.The reactivity of bridged cycloalkanes is substantially greater than that of cycloalkenes, but that of cyclo-pentadiene dimer is anomalously small.For allylic substrates, the correlation of electron density at the double bond with reactivity is shown by a rectilinear relationship between log k and ?I.Allyl iodide and allyl alcohol are anomalously more reactive than this correlation would predict; this is accounted for by solvation and by internal solvation effects respectively.
