Check Digit Verification of cas no

The CAS Registry Mumber 219480-94-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,4,8 and 0 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 219480-94:
(8*2)+(7*1)+(6*9)+(5*4)+(4*8)+(3*0)+(2*9)+(1*4)=151
151 % 10 = 1
So 219480-94-1 is a valid CAS Registry Number.

Synthesis and alkylation of pyridylacetylenes under phase transfer catalysis conditions in a liquid/solid system

Abele,Abele,Ruhina,Gaukhman,Lukevics

, p. 459 - 462 (1998)

We have investigated the alkylation of 2-methyl-5-ethynylpyridine by butyl bromide in liquid/liquid and liquid/solid two-phase catalytic systems. We have shown that the catalytic system solid KOH/18-crown-6/CuBr/toluene is the most active in this reaction; using this system, we obtained alkylation products of ethynylpyridines in 34-43% yields. 1998 Plenum Publishing Corporation.
