Calculate Digit Verification of CAS Registry Number 89959-33:
(7*8)+(6*9)+(5*9)+(4*5)+(3*9)+(2*3)+(1*3)=211
211 % 10 = 1
So 89959-33-1 is a valid CAS Registry Number.

Synthesis of Some Dihydroxamic Acid Siderophores

Das, M. K.,Bose, P.,Roy, N.

, p. 345 - 348 (2007/10/02)

Twenty-two new dihydroxamic acids having the general formula (CH2)n2 (n = 2, 3, 4, 6, 8; R = H, aryl) have been synthesized either by condensation of the acid chlorides with suitable arylhydroxylamines or by the reaction of the esters with hydroxylamine and characterized by elemental analyses and infrared, UV, and proton NMR spectra.
