Check Digit Verification of cas no

The CAS Registry Mumber 612840-22-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,1,2,8,4 and 0 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 612840-22:
(8*6)+(7*1)+(6*2)+(5*8)+(4*4)+(3*0)+(2*2)+(1*2)=129
129 % 10 = 9
So 612840-22-9 is a valid CAS Registry Number.

Remarkable Change of the Diastereoselection in the Dye-Sensitized Ene Hydroperoxidation of Chiral Alkenes by Zeolite Confinement

Stratakis, Manolis,Kalaitzakis, Dimitris,Stavroulakis, Dimitris,Kosmas, Giannis,Tsangarakis, Constantinos

, p. 3471 - 3474 (2003)

(Equation presented) The ene reaction of singlet oxygen with chiral trisubstituted alkenes bearing an alkyl and a phenyl group at the stereogenic center is erythro diastereoselective in solution and threo diastereoselective if carried out within zeolite Na-Y. The change of the diastereoselection trend by zeolite confinement is attributed to a synergism of steric effects and cation-π interactions.
