196865-24-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 196865-24-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,6,8,6 and 5 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 196865-24:
(8*1)+(7*9)+(6*6)+(5*8)+(4*6)+(3*5)+(2*2)+(1*4)=194
194 % 10 = 4
So 196865-24-4 is a valid CAS Registry Number.

Concerning the Enantiomerization Barrier of Hypericin
Altmann,Etzlstorfer,Falk
, p. 361 - 370 (2007/10/03)
The Syntheses of ω-(R)-menthyl and ω,ω′-bis-(R)-menthyl derivatives 2 and 3 of hypericin were achieved, and the corresponding diastereomers could be separated. The equilibria between the respective diastereomers are slightly displaced in favor of the chro
