Check Digit Verification of cas no
The CAS Registry Mumber 452081-58-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,2,0,8 and 1 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 452081-58:
(8*4)+(7*5)+(6*2)+(5*0)+(4*8)+(3*1)+(2*5)+(1*8)=132
132 % 10 = 2
So 452081-58-2 is a valid CAS Registry Number.

The enol ether 7 was prepared by cleavage of the N-O bond of the known isoxazolidine 3, followed by N-alkylation to 4, silylation and oxidation to the N-oxide 6, and Cope elimination. Cu-Catalysed cyclopropanation of 7 led to the diastereoisomeric cyclopr
