93866-51-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 93866-51-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,8,6 and 6 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 93866-51:
(7*9)+(6*3)+(5*8)+(4*6)+(3*6)+(2*5)+(1*1)=174
174 % 10 = 4
So 93866-51-4 is a valid CAS Registry Number.

A New Approach to Neoflavonoid Synthesis
Donnelly, Dervilla M. X.,Finet, Jean-Pierre,Guiry, Patrick J.,Hutchinson, Rhona M.
, p. 2851 - 2852 (2007/10/02)
Neoflavonoids or 4-arylcoumarins are prepared by arylation of 3-hydroxycoumarins with aryl-lead triacetates followed by palladium-catalysed reduction of the derived 3-trifluoromethylsulphonyloxyarylcoumarins.
