121733-40-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121733-40-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,7,3 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 121733-40:
(8*1)+(7*2)+(6*1)+(5*7)+(4*3)+(3*3)+(2*4)+(1*0)=92
92 % 10 = 2
So 121733-40-2 is a valid CAS Registry Number.

The Configuration of 1,2-Diketone Hydrazone Oximes
Gnichtel, Horst,Toepper, Bernhard
, p. 1071 - 1074 (2007/10/02)
The configuration of 1,2-diketone (Z)-hydrazone (E)-oximes 3a-c was determined by ring closure with formaldehyde to 1,2,4-triazine 4-oxides 5a-c and the tautomeric 4-hydroxy-1,2,4-triazines 6a-c and by Beckmann reaction to 1,2,4 triazoles 8a-c.From benzil
