140224-91-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 140224-91-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,2,2 and 4 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 140224-91:
(8*1)+(7*4)+(6*0)+(5*2)+(4*2)+(3*4)+(2*9)+(1*1)=85
85 % 10 = 5
So 140224-91-5 is a valid CAS Registry Number.

A shorter route to the synthesis of (+)-junenol isojunenol, and their coumarate esters from (-)-santonin
Cardona, Luz,Garcia, Begona,Gimenez, J. Enric,Pedro, Jose R.
, p. 851 - 860 (2007/12/18)
This paper reports on the chemical conversion of (-)-santonin into (+)-junenol, isojunenol and their coumarate esters. The identity of (+)-junenol and 8-epi-β-verbesinol is also established.
