33843-75-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 33843-75-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,8,4 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 33843-75:
(7*3)+(6*3)+(5*8)+(4*4)+(3*3)+(2*7)+(1*5)=123
123 % 10 = 3
So 33843-75-3 is a valid CAS Registry Number.

Perfluoro-1,3,4-oxadiazoles
Vasiliev, N. V.,Lyashenko, Yu. E.,Patalakha, A. E.,Sokolski, G. A.
, p. 227 - 232 (1993)
Some new polyfluorinated 1,3,4-oxadiazoles have been obtained via a two-step method.The cycloadditions of the 1,3,4-oxadiazoles have been studied and an analysis of the energies of the frontier orbitals calculated by the MNDO method indicates a LUMO-dependent pathway for cycloaddition.
