Check Digit Verification of cas no
The CAS Registry Mumber 16219-33-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,2,1 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 16219-33:
(7*1)+(6*6)+(5*2)+(4*1)+(3*9)+(2*3)+(1*3)=93
93 % 10 = 3
So 16219-33-3 is a valid CAS Registry Number.

Thermal Behaviour of 3-Phenyl-1,2,4-oxadiazol-5-ylhydrazines
Adembri, Giorgio,Camparini, Alfredo,Ponticelli, Fabio,Tedeschi, Piero
, p. 1703 - 1706 (2007/10/02)
Depending on the substitution on the hydrazine moiety, thermolysis of 3-phenyl-1,2,4-oxadiazol-5-ylhydrazines (1)-(5) gives variable amounts of 1-amino-Δ2-1,2,4-triazolin-5-ones (13) or (17), Δ2- or Δ3-1,2,4-triazolin-5-ones (12), (18), or (19), and the s-triazine (20).A possible mechanism accounting for the products and the effects is discussed.A diradical intermediate and a hydrogen transfer from the reaction medium are suggested on the basis of the effect of benzoyl peroxide on the reaction and on the behaviour of the hydrazines (1)-(4) towards catalytic hydrogenation.
