398142-31-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 398142-31-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,9,8,1,4 and 2 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 398142-31:
(8*3)+(7*9)+(6*8)+(5*1)+(4*4)+(3*2)+(2*3)+(1*1)=169
169 % 10 = 9
So 398142-31-9 is a valid CAS Registry Number.

A highly enantioselective intramolecular heck reaction with a monodentate ligand
Imbos, Rosalinde,Minnaard, Adriaan J.,Feringa, Ben L.
, p. 184 - 185 (2007/10/03)
An efficient enantioselective intramolecular Heck reaction of cyclohexadienones, using readily available and modular TADDOL-based mono- and bidentate phosphoramidites as chiral ligands and not requiring any additives, has been developed. Excellent enantio
