161808-00-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 161808-00-0 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 8 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 161808-00:
(8*1)+(7*6)+(6*1)+(5*8)+(4*0)+(3*8)+(2*0)+(1*0)=120
120 % 10 = 0
So 161808-00-0 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
