Check Digit Verification of cas no

The CAS Registry Mumber 155086-19-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,0,8 and 6 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 155086-19:
(8*1)+(7*5)+(6*5)+(5*0)+(4*8)+(3*6)+(2*1)+(1*9)=134
134 % 10 = 4
So 155086-19-4 is a valid CAS Registry Number.

Formation of azomethine ylids by thermolysis of oxazolidines. Study of the reaction in solution and in the gaseous phase

Bureau, R.,Mortier, J.,Joucla, M.

, p. 584 - 596 (2007/10/02)

Thermolysis of oxazolidines leads to azomethine ylids via cycloreversion.In the liquid phase, these intermediates then give 1-3 dipolar cycloaddition; in the gaseous phase, they lead to aziridines.With an alkyl group in position 2, we observed also the formation of enamines.The effect of substituents on both the cycloreversion reaction and the evolution of azomethine ylids was studied.The mechanism of the process tautomerism aziridine -> azomethine ylid -> enamine is discussed.Keywords - azomethine ylids / oxazolidines / cycloreversion / aziridines / enamines / tautomerism
