Check Digit Verification of cas no

The CAS Registry Mumber 2594-02-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,9 and 4 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2594-02:
(6*2)+(5*5)+(4*9)+(3*4)+(2*0)+(1*2)=87
87 % 10 = 7
So 2594-02-7 is a valid CAS Registry Number.

Synthesis of hydroxamic acids by activation of carboxylic acids with N,N'-carbonyldiimidazole: Exploring the efficiency of the method

Usachova, Natalija,Leitis, Gundars,Jirgensons, Aigars,Kalvinsh, Ivars

, p. 927 - 935 (2010)

Activation of carboxylic acids with N,N'-carbonyldiimidazole followed by the reaction with anhydrous or aqueous hydroxylamine hydrochloride was demonstrated to be an operationally simple method for the synthesis of hydroxamic acids in good yield and high purity after aqueous workup. The potential by-product, N,O-diacylhydroxylamine, is cleanly transformed to hydroxamic acid in these reaction conditions.
