Check Digit Verification of cas no
The CAS Registry Mumber 21947-76-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,9,4 and 7 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 21947-76:
(7*2)+(6*1)+(5*9)+(4*4)+(3*7)+(2*7)+(1*6)=122
122 % 10 = 2
So 21947-76-2 is a valid CAS Registry Number.

Radical Reactions of Epoxides. Chlorine Atom Abstraction from α- and β-Chloro Epoxides by the Triphenyltin Radical

The four isomers of chloroepoxypropane have been prepared, and their relative reactivities with triphenyltin haydride have been determined.The three α-chloroepoxypropanes react at a much slower rate than does epichlorohydrin, the only β-chloro epoxide of the four.The nature of the increased reactivity for the β-chloro epoxides has been investigated by studying two pair of diastereomeric β-chloro epoxides, and a single acyclic β-chloro ether.The results are discussed in terms of the inductive, and stereoelectronic effects of the epoxide.
