Calculate Digit Verification of CAS Registry Number 82631-94:
(7*8)+(6*2)+(5*6)+(4*3)+(3*1)+(2*9)+(1*4)=135
135 % 10 = 5
So 82631-94-5 is a valid CAS Registry Number.

Synthesis of novel C2-symmetric ligands based on (R,R)- and (S,S)- diphenyl-1,3-propanediol

Roos, Gregory H. P.,Donovan, A. Richard

, p. 991 - 1000 (1999)

A range of novel C2-symmetric dioxygen and dinitrogen ligands can readily be obtained through the interconversion of the parent 1,3-diphenyl- 1,3-propanediol enantiomers which are, in turn, accessed in good yields via a Sharpless asymmetric epoxidative resolution.
