109491-18-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109491-18-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,4,9 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 109491-18:
(8*1)+(7*0)+(6*9)+(5*4)+(4*9)+(3*1)+(2*1)+(1*8)=131
131 % 10 = 1
So 109491-18-1 is a valid CAS Registry Number.

STUDIES ON THE REDUCTION OF CYCLIC 1,3-DIKETONES VIA THEIR TRIFLATES
Martinez, A. Garcia,Alvarez, R. Martinez,Casado, M. Madueno,Subramanian, L. R.,Hanack, M.

Using 1,3-Cyclohexadione (1) and 5,5-dimethyl-1,3-Cyclohexadione (11) as examples, it is shown that 1,3-diketones can be transformed into monoketones, monoalcohols, alkanes and unsaturated ketones.
