Check Digit Verification of cas no

The CAS Registry Mumber 100186-76-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,1,8 and 6 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 100186-76:
(8*1)+(7*0)+(6*0)+(5*1)+(4*8)+(3*6)+(2*7)+(1*6)=83
83 % 10 = 3
So 100186-76-3 is a valid CAS Registry Number.

Two-Phase Reaction of 1-Bromooctane with Sodium Acetate and Potassium Acetate Catalyzed by Diquaternary Ammonium Salts

Schiefer, H.,Beger, J.,Lorenz, U.

, p. 383 - 398 (2007/10/02)

New unsaturated diquaternary ammonium salts (diquats) were prepared in two ways from ditertiary amines 3 and 1-bromoalkanes or from 1,4-dibromobut-2t-ene and tertiary monoamines.A comparison of their catalytic ability with that of saturated diquats and with that of corresponding monoquats was made.The reaction of n-C8H17Br with NaOAc or KOAc in the two phase system liquid-liquid without an additional solvent is catalyzed more effectively by the unsaturated diquats than by the saturated diquats and the monoquats.Most of the used quats catalyze the ester formation from NaOAc more effectively in the system liquid-liquid, however, the ester formation from KOAc more effectively in the system solid-liquid; KOAc is generally superior to NaOAc in both systems.Consequently, in the phase-transfer catalyzed ester formation from alkali acetate and alkyl halides not only the structure of the quat but also the inorganic cation of the acetate have influence on the rate of conversion.
