78051-40-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 78051-40-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,0,5 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 78051-40:
(7*7)+(6*8)+(5*0)+(4*5)+(3*1)+(2*4)+(1*0)=128
128 % 10 = 8
So 78051-40-8 is a valid CAS Registry Number.

TAUTOMERISM IN THE BENZOYLHYDRAZONES OF METHYL 4-ARYL-2,4-DIOXOBUTYRATES
Yakimovich, S. I.,Nikolaev, V. N.
, p. 234 - 240 (2007/10/02)
By PMR spectroscopy it was shown that the benzoylhydrazones of methyl 4-aryl-2,4-dioxobutyrates exist in deuterochloroform solutions as tautomeric mixtures of the configurational isomers of the ketohydrazone and cyclic 5-hydroxypyrazoline forms.The equili
