33626-64-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 33626-64-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,6,2 and 6 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 33626-64:
(7*3)+(6*3)+(5*6)+(4*2)+(3*6)+(2*6)+(1*4)=111
111 % 10 = 1
So 33626-64-1 is a valid CAS Registry Number.

Δ2-1,2,4-oxadiazolines by condensation of amidoximes with ketones and aldehydes
Lessel
, p. 383 - 389 (2007/10/02)
Using acetic acid as a solvent, ketones and aromatic aldehydes react with amidoximes 1 to cyclic products, Δ2-1,2,4-oxadiazolines 3. The lack of reactivity in neutral milieu is explained by MNDO calculations. Protonated carbonyl compounds are discussed to be the reactive species.
