Check Digit Verification of cas no

The CAS Registry Mumber 22985-85-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,9,8 and 5 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 22985-85:
(7*2)+(6*2)+(5*9)+(4*8)+(3*5)+(2*8)+(1*5)=139
139 % 10 = 9
So 22985-85-9 is a valid CAS Registry Number.

MECANISME DE L'ADDITION NUCLEOPHILE AU GROUPEMENT CARBONYLE-I. INFLUENCE DE LA NATURE DU SUBSTITUANT POLAIRE SUR LA STEREOCHIMIE ET LA REACTIVITE DANS LES REACTIONS D'ADDITION DE BROMURE DE METHYLMAGNESIUM AUX ARYL-1 PHENYL-2 PROPANONES

Lasperas, M.,Perez-Rubalcaba, A.,Quiroga-Feijoo, M. L.

, p. 3403 - 3408 (2007/10/02)

The influence of a m- or p-polar substituent in 1-aryl 2-phenyl propanones, on addition reactions with CH3MgBr in ether at 30 deg C has been investigated.The invariability of asymmetric induction as a function of substituent, and the correlation of rate constant ratios with Hammett ? constants (ρ=0.24, r=0.97), are consistent with a four-centre pericyclic concerted mechanism with concomitant departure of a solvent molecule.
