Check Digit Verification of cas no
The CAS Registry Mumber 13670-33-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,6,7 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 13670-33:
(7*1)+(6*3)+(5*6)+(4*7)+(3*0)+(2*3)+(1*3)=92
92 % 10 = 2
So 13670-33-2 is a valid CAS Registry Number.

Synthesis of 2-Vinyl-2-oxazoline by Isomerisation of N-Acryloylaziridine
Woo, H.G.
, p. 1114 (2007/10/02)
2-Vinyl-2-oxazoline (3) is quantitatively obtained by the isomerisation of N-acryloylaziridine (1) at room temperature in the presence of potassium thiocyanate in dimethyl sulphoxide-hexamethylphosphoric acid triamide (HMPT)(9:1, v/v).It is found that the introduction of electron-withdrawing substituent into acryloyl group facilitates the isomerisation reaction.
