1334473-21-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1334473-21-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,4,4,7 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1334473-21:
(9*1)+(8*3)+(7*3)+(6*4)+(5*4)+(4*7)+(3*3)+(2*2)+(1*1)=140
140 % 10 = 0
So 1334473-21-0 is a valid CAS Registry Number.

Catalytic enantioselective diboration of cyclic dienes. a modified ligand with general utility
Hong, Kai,Morken, James P.
, p. 9102 - 9108 (2011/12/15)
The enantioselective 1,4-diboration of cyclic dienes with a new taddol-derived phosphonite ligand occurs with excellent enantioselectivity. Oxidation delivers the derived 1,4-diol, whereas homologation can be used to deliver a chiral 1,6-diol.
