5307-59-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5307-59-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,0 and 7 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5307-59:
(6*5)+(5*3)+(4*0)+(3*7)+(2*5)+(1*9)=85
85 % 10 = 5
So 5307-59-5 is a valid CAS Registry Number.

Aryllead-mediated synthesis of linear 3-arylpyranocoumarins: synthesis of robustin and robustic acid
Donnelly, Dervilla M. X.,Molloy, David J.,Reilly, John P.,Finet, Jean-Pierre
, p. 2531 - 2534 (2007/10/02)
The two naturally occurring linear 3-arylpyranocoumarins, robustin 1 and robustic acid 2, have been synthesised in nine steps from methyl 2,4,6-trihydroxyphenyl ketone, in 19percent overall yield for robustin and 18percent for robustic acid.Their synthese
