140397-00-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 140397-00-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,3,9 and 7 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 140397-00:
(8*1)+(7*4)+(6*0)+(5*3)+(4*9)+(3*7)+(2*0)+(1*0)=108
108 % 10 = 8
So 140397-00-8 is a valid CAS Registry Number.

An Alternative Synthesis of Both Enantiomers of trans-3,4-Bis(benzyloxy)cyclopentanone
Raeppel, Stéphane,Toussaint, Dominique,Suffert, Jean
, p. 1061 - 1062 (2007/10/03)
An efficient synthesis of both enantiomers of trans-3,4-bis(benzyloxy)cyclopentanone 4, potential precursors to the five-membered (A)-ring of the neocarzinostatin chromophore, was accomplished from diethyl tartrate in 7 steps.
