158233-84-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 158233-84-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,2,3 and 3 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 158233-84:
(8*1)+(7*5)+(6*8)+(5*2)+(4*3)+(3*3)+(2*8)+(1*4)=142
142 % 10 = 2
So 158233-84-2 is a valid CAS Registry Number.

Ketone-directed peracid epoxidation of cyclic alkenes
Armstrong, Alan,Barsanti, Paul A.,Clarke, Paul A.,Wood, Anthony
, p. 1373 - 1380 (1996)
Ketone carbonyl groups are shown to direct the peracid epoxidation of cyclic alkenes with greater selectivity than that displayed by esters. An 18O labelling study is used to show that a dioxirane intermediate is not involved in these reactions.
