Check Digit Verification of cas no

The CAS Registry Mumber 1234566-21-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,4,5,6 and 6 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1234566-21:
(9*1)+(8*2)+(7*3)+(6*4)+(5*5)+(4*6)+(3*6)+(2*2)+(1*1)=142
142 % 10 = 2
So 1234566-21-2 is a valid CAS Registry Number.

Rhodium-Catalyzed asymmetric synthesis of spirocarbocycles: arylboron reagents as surrogates of 1,2-dimetalloarenes

Shintani, Ryo,Isobe, Shingo,Takeda, Momotaro,Hayashi, Tamio

supporting information; experimental part, p. 3795 - 3798 (2010/08/20)

(Figure Presented) Revolutionary Rh-oad: A rhodium/dienecatalyzed addition of sodium tetraarylborates to alkyne-tethered 2-cydoalken-lones has been developed for the synthesis of splrocarbocycles. The tetraarylborates catalytlcally form two new carbon-carbon bonds. A chlral diene ligand also asymmetrically creates quaternary spirocarbon stereocenters with high enantiomeric purity.
