Check Digit Verification of cas no
The CAS Registry Mumber 220867-41-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,8,6 and 7 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 220867-41:
(8*2)+(7*2)+(6*0)+(5*8)+(4*6)+(3*7)+(2*4)+(1*1)=124
124 % 10 = 4
So 220867-41-4 is a valid CAS Registry Number.

Process for preparing 2-cyanoindan-1-ones
-
, (2008/06/13)
In a particularly advantageous process for producing 2-cyanoindan-1-ones from 2-halogenated indan-1-ones by reaction with a cyanide salt, the cyanide salt is dissolved in a dipolar aprotic solvent or in a water-miscible ether and 2-halogenated indan-1-one is metered into this solution.
