131575-56-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131575-56-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,5,7 and 5 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 131575-56:
(8*1)+(7*3)+(6*1)+(5*5)+(4*7)+(3*5)+(2*5)+(1*6)=119
119 % 10 = 9
So 131575-56-9 is a valid CAS Registry Number.

, 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.
