161807-99-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 161807-99-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,8,0 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 161807-99:
(8*1)+(7*6)+(6*1)+(5*8)+(4*0)+(3*7)+(2*9)+(1*9)=144
144 % 10 = 4
So 161807-99-4 is a valid CAS Registry Number.

IMINE-ENAMINE TAUTOMERISM OF TROPANONE SCHIFF'S BASES
Kostochka, L. M.,Lezina, V. P.
, p. 335 - 339 (2007/10/02)
Using PMR spectroscopy, we have demonstrated the existence of an imine-enamine tautomerism and optically active forms in tropanone Schiff's bases.We have studied the effect of solvents and substituents on the tautomeric equilibrium of the system.By reacti
