Check Digit Verification of cas no

The CAS Registry Mumber 1267636-45-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,7,6,3 and 6 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1267636-45:
(9*1)+(8*2)+(7*6)+(6*7)+(5*6)+(4*3)+(3*6)+(2*4)+(1*5)=182
182 % 10 = 2
So 1267636-45-2 is a valid CAS Registry Number.

Enantioselective haloetherification by asymmetric opening of meso -halonium ions

Hennecke, Ulrich,Mueller, Christian H.,Froehlich, Roland

supporting information; experimental part, p. 860 - 863 (2011/05/03)

A new approach to enantioselective haloetherification reactions via desymmetrization of in situ-generated meso-halonium ions is described. The combination of N-haloamides as a halogen source and sodium salts of chiral phosphoric acids as catalysts can be used for the cyclization of symmetrical ene-diol substrates, yielding the haloetherification products under practical conditions in enantioenriched form.(Figure Presented)
