Check Digit Verification of cas no

The CAS Registry Mumber 1289403-24-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,9,4,0 and 3 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1289403-24:
(9*1)+(8*2)+(7*8)+(6*9)+(5*4)+(4*0)+(3*3)+(2*2)+(1*4)=172
172 % 10 = 2
So 1289403-24-2 is a valid CAS Registry Number.

Rhodium/chiral diene-catalyzed asymmetric cyclopolymerization of achiral 1,8-diynes

Ichikawa, Yoshitaka,Nishimura, Takahiro,Hayashi, Tamio

, p. 2342 - 2348 (2011)

Cyclopolymerization of nitrogen-bridged 1,8-diynes containing one terminal and one internal alkyne in the presence of a rhodium/chiral diene catalyst gave enantiomerically enriched polymers with a helix chirality that keep their chiral structures in solut
