Check Digit Verification of cas no

The CAS Registry Mumber 111969-33-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,9,6 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 111969-33:
(8*1)+(7*1)+(6*1)+(5*9)+(4*6)+(3*9)+(2*3)+(1*3)=126
126 % 10 = 6
So 111969-33-6 is a valid CAS Registry Number.

RING-OPENING REACTION OF THE 1,3-DIAZETIDINE RING: HYDRAZINOLYSIS OF 2,4-BIS(HETEROARYLIMINO)-1,3-DIAZETIDINE DERIVATIVES

Molina, P.,Alajarin, M.,Lopez-Leonardo, C.,Elguero, J.,Claramunt, R. M.

, p. 791 - 798 (2007/10/02)

Reaction between 1,3-diaryl-2,4-bis(heteroarylimino)-1,3-diazetidines and anhydrous hydrazine yield 4-aryl-3-heteroarylimino-5-arylamino-2H-2,3-dihydro-1,2,4-triazoles.When methylhydrazine is used instead of hydrazine 1-methyl and, in some cases, 2-methyl derivatives were isolated.A tentative mechanism is proposed for the different compounds, which were fully characterized by mass spectrometry and 1H and 13C n.m.r. spectroscopy.
