43205-85-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 43205-85-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,3,2,0 and 5 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 43205-85:
(7*4)+(6*3)+(5*2)+(4*0)+(3*5)+(2*8)+(1*5)=92
92 % 10 = 2
So 43205-85-2 is a valid CAS Registry Number.

Stereoselective synthesis of (6R)- and (6S)-diosphenol and Ψ-diosphenol
Schneider, David F,Viljoen, Murray S
, p. 5307 - 5315 (2007/10/03)
Methods are discussed for the stereoselective synthesis of the (R)-and (S)-enantiomers of the diosphenols (5)-(8) by utilizing the commercially available stereoisomers (9), (12), (23) and (25) of carvone and limonene, respectively, as chiral starting materials.
