Check Digit Verification of cas no

The CAS Registry Mumber 141621-27-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,6,2 and 1 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 141621-27:
(8*1)+(7*4)+(6*1)+(5*6)+(4*2)+(3*1)+(2*2)+(1*7)=94
94 % 10 = 4
So 141621-27-4 is a valid CAS Registry Number.

Phase-transfer-catalysed Preparation of N-Alkylated Trihydroxamic Acids

Hoffmann, Pascal,Doucet, Jean-Baptiste,Li, Wenhao,Vergnes, Laurent,Labidalle, Serge

, p. 218 - 219 (2007/10/03)

We describe a synthetic route involving phase transfer catalysis leading to a series of tripodal N-alkylated hydroxamic acids as models of desferrioxamine; iron(III) exchange reactions between their iron complexes and EDTA were investigated.
