Check Digit Verification of cas no

The CAS Registry Mumber 78217-89-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,2,1 and 7 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 78217-89:
(7*7)+(6*8)+(5*2)+(4*1)+(3*7)+(2*8)+(1*9)=157
157 % 10 = 7
So 78217-89-7 is a valid CAS Registry Number.

New synthetic probes of the iron transport system of Paracoccus denitrificans

Buckley, George M.,Pattenden, Gerald,Whiting, Donald A.

, p. 11781 - 11792 (2007/10/02)

A range of analogues of parabactin A 4 and agrobactin A 5 have been synthesised. All these compounds were able to chelate iron, and to promote the growth of iron-starved Paracoccus denitrificans to varying degrees. A degree of flexibility in the sideropho

Synthesis of Parabactin Analogues and Formation of Transition Metal Complexes of Parabactin and Related Compounds

, p. 1542 - 1550 (2007/10/02)

Transition metal complexes of parabactin and its related synthetic spermidine catecholamides which lack the central o-hydroxyphenyloxazoline were studied by the potentiometric titration method, e.s.r. spectroscopy, and fast atom bombardment mass spectrometry (FAB-MS).Direct mass spectral sampling of the parabactin-Fe(III) complex in glycerol solution was first achieved by FAB-MS spectrometry, confirming that the composition of the parabactin-Fe(III) complex is (2-)*2Na(1+) and that the iron(III) ion binds with two catechols and an o-hydroxyphenyl-Δ2-oxazoline moiety in NaOH solution.The e.s.r. g value (4.5) of the parabactin-Fe(III) complex differed from those (4.3) of the 3:1 catechol-Fe(III) complex and other parabactin-related catecholamide-Fe(III) complexes.These results suggest that the structure of the parabactin-Fe(III) complex differs considerably from the regular octahedral structure of the 3:1 catechol-Fe(III) complex and may have a structure similar to the ferrimycobactin P-Fe(III) complex, in which the iron(III) lies exposed in a splayed V-shaped cleft and binds with five oxygens and one nitrogen in a very strained octahedron.
