Check Digit Verification of cas no

The CAS Registry Mumber 2049-66-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,4 and 9 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 2049-66:
(6*2)+(5*0)+(4*4)+(3*9)+(2*6)+(1*6)=73
73 % 10 = 3
So 2049-66-3 is a valid CAS Registry Number.

Alkylation of Monosubstituted Malonate Anions With Pyridinium and Quinolinium Salts

Katritzky, Alan R.,Aurrecoechea, Jose M.

, p. 342 - 345 (2007/10/02)

Monosubstituted malonate anions are alkylated at room temperature with 1-(sec-alkyl)quinolinium salts.Hindered disubstituted malonate esters can thus be prepared under very mild conditions.
