Check Digit Verification of cas no

The CAS Registry Mumber 63285-19-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,2,8 and 5 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 63285-19:
(7*6)+(6*3)+(5*2)+(4*8)+(3*5)+(2*1)+(1*9)=128
128 % 10 = 8
So 63285-19-8 is a valid CAS Registry Number.

HYDROLYSE BASIQUE ET DECARBOXYLATION D'ESTERS ALLOPHANIQUES EN MILIEU MIXTE ACETONITRILE-EAU: CATALYSE BIFONCTIONNELLE PAR UNE ENTITE FORMEE ENTRE BASE ET SOLVANT

Monnier, E.,Klaebe, A,Perie, J. J.

, p. 3067 - 3070 (1983)

Base catalysed hydrolysis of allophanic esters-models of carboxybiotine- in acetonitrile/water mixture, shows a sharp increase in rate constant in the range of 0.1-0.3 M in water, with a maximum which is interpreted as a balance between two desolvation terms, one concerning the nucleophile, the other the anionic transition state.Moreover, in acetonitrile/water mixtures at low water content (2.10-2 M), a fast hydrolysis (kexpca.0.5 s-1 at 20 deg C) of allophanic esters (carboxy-biotin models) is observed due to catalysis by the enolate of acetamide.This speciesalso catalyses the decarboxylation step, likely behaving as a bifunctional catalyst.
