Check Digit Verification of cas no
The CAS Registry Mumber 140169-47-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,1,6 and 9 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 140169-47:
(8*1)+(7*4)+(6*0)+(5*1)+(4*6)+(3*9)+(2*4)+(1*7)=107
107 % 10 = 7
So 140169-47-7 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.
