Check Digit Verification of cas no

The CAS Registry Mumber 902493-71-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,2,4,9 and 3 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 902493-71:
(8*9)+(7*0)+(6*2)+(5*4)+(4*9)+(3*3)+(2*7)+(1*1)=164
164 % 10 = 4
So 902493-71-4 is a valid CAS Registry Number.

Simple transformation of crystalline chiral natural anions to liquid medium and their use to induce chirality

Branco, Luis C.,Gois, Pedro M. P.,Lourenco, Nuno M. T.,Kurteva, Vanya B.,Afonso, Carlos A. M.

, p. 2371 - 2372 (2008/09/16)

New chiral ionic liquids can be prepared simply by combining the tetra-n-hexyl-dimethylguanidinium cation with readily available chiral anions and used as an asymmetric inducing agent as demonstrated for catalytic Rh(ii) carbenoid C-H insertion and Sharpless dihydroxylation. The Royal Society of Chemistry 2006.
