77745-80-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77745-80-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,7,4 and 5 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 77745-80:
(7*7)+(6*7)+(5*7)+(4*4)+(3*5)+(2*8)+(1*0)=173
173 % 10 = 3
So 77745-80-3 is a valid CAS Registry Number.

N-Oxide/Enhydroxylamine Tautomerism of 4-Benzyl-2-oxo-3-imidazoline 3-Oxides
Gnichtel, Horst,Beier, Maria
, p. 312 - 316 (2007/10/02)
The 4-Benzyl-2-oxo-3-imidazoline 3-oxides 5a-c were prepared by cyclisation of the phenyl substituted (E)-3-amino-3-methyl-1-phenyl-2-butanone oximes 4a-c with phosgene.Rising temperature, the N-oxides 5 tautomerize to the 4-benzylidene-3-hydroxy-2-imidaz
