Check Digit Verification of cas no
The CAS Registry Mumber 103750-03-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,7,5 and 0 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 103750-03:
(8*1)+(7*0)+(6*3)+(5*7)+(4*5)+(3*0)+(2*0)+(1*3)=84
84 % 10 = 4
So 103750-03-4 is a valid CAS Registry Number.

Syntheses of siderophore-drug conjugates using a convergent thiol-maleimide system
Juarez-Hernandez, Ral E.,Miller, Patricia A.,Miller, Marvin J.
supporting information, p. 799 - 803 (2013/01/15)
Three siderophore-drug conjugates (sideromycins) were synthesized by preparation of a maleimide linked derivative of the siderophore desferrioxamine B and reacting the corresponding Ga3+-complex with freshly prepared thiol-containing antibiotics: loracarbef, ciprofloxacin, and nadifloxacin. The conjugates and their synthetic precursors were tested against a broad panel of bacteria and were found to display Gram-positive selective, growth inhibitory activity (μM), indicating that this approach is suitable for the convergent syntheses and screening of novel sideromycins.
