Check Digit Verification of cas no

The CAS Registry Mumber 1333259-97-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,3,2,5 and 9 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1333259-97:
(9*1)+(8*3)+(7*3)+(6*3)+(5*2)+(4*5)+(3*9)+(2*9)+(1*7)=154
154 % 10 = 4
So 1333259-97-4 is a valid CAS Registry Number.

Modular monodentate oxaphospholane ligands: Utility in highly efficient and enantioselective 1,4-diboration of 1,3-dienes

Schuster, Christopher H.,Li, Bo,Morken, James P.

supporting information; experimental part, p. 7906 - 7909 (2011/10/09)

Tune it up! Tunable, chiral, monodentate oxaphospholane ligands (termed OxaPhos) are highly effective in the Pt-catalyzed title reaction, providing the 1,4-addition products in enantiomer ratios approaching 99:1 (see scheme). In the presence of enantiomerically pure cis-iBu-OxaPhos, a catalyst loading of only 0.02 mol% [Pt(dba)3] was sufficient for effective reaction. pin=pinacolato, dba=dibenzylideneacetone.
