Check Digit Verification of cas no
The CAS Registry Mumber 90088-46-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,0,8 and 8 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 90088-46:
(7*9)+(6*0)+(5*0)+(4*8)+(3*8)+(2*4)+(1*6)=133
133 % 10 = 3
So 90088-46-3 is a valid CAS Registry Number.

Ring-opening reactions of cyclopropanes. Part 8.1 Nitrosation of donor-acceptor cyclopropanes

The reaction of 2,2-dialkoxycyclopropane-1-carboxylates 1a-d and monoalkoxycyclopropane 1e with NOCl gives isoxazoline- and/or isoxazole-3-carboxylates by regioselective ring-opening at C1-C2 bond. A mechanistic interpretation suggests the intermediacy of well-stabilised dipolar species.
