The CAS Registry Mumber 74880-37-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,8,8 and 0 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 74880-37:
(7*7)+(6*4)+(5*8)+(4*8)+(3*0)+(2*3)+(1*7)=158
158 % 10 = 8
So 74880-37-8 is a valid CAS Registry Number.

Addition of arenesulphenyl chlorides to 2-methylenebicyclohept-5-ene: effect of increasing electron demand upon the rate and product determining transition states

Garratt, Dennis G.,Beaulieu, Pierre L.,Morisset, Veronique M.

, p. 1021 - 1029 (2007/10/02)

The rates and products of addition of a series of sixteen arenesulphenyl chlorides to 2-methylenebicyclohept-5-ene, 7, and the E,Z isomeric 2-ethylidenebicyclohept-5-enes, 8, and 9, have been determined in methylene chloride solution.The major species from attack on 7 is always endo-3-arylthio-1-chloromethyltricyclo2,6>heptane, the product of exo attack upon the endocyclic double bond with homoallylic participation of the exocyclic Π system.No evidence was found for initial electrophilic attack upon the exocyclic double bond.
