197517-41-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 197517-41-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,5,1 and 7 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 197517-41:
(8*1)+(7*9)+(6*7)+(5*5)+(4*1)+(3*7)+(2*4)+(1*1)=172
172 % 10 = 2
So 197517-41-2 is a valid CAS Registry Number.

Ochratoxin A acts as a photoactivatable DNA cleaving agent

Gillman, Ivan G.,Yezek, Jennifer M.,Manderville, Richard A.

, p. 647 - 648 (1998)

The ability of ochratoxin A to photoinduce DNA cleavage is described; in the presence of DNA the photoreaction yields the non-chlorinated derivative, ochratoxin B, while a hydroquinone derivative is produced under anaerobic conditions.

Effect of the mimic structure on the molecular recognition properties of molecularly imprinted polymers for ochratoxin A prepared by a fragmental approach

Baggiani, Claudio,Biagioli, Flavia,Anfossi, Laura,Giovannoli, Cristina,Passini, Cinzia,Giraudi, Gianfranco

, p. 833 - 837 (2013/07/19)

In this work the fragmental approach was used to prepare several molecularly imprinted ethylene dimethacrylate-co-methacrylic acid polymers with molecular recognition towards the mycotoxin ochratoxin A, with the aim of searching for simpler mimic template

The synthesis of bromo- and iodo-ochratoxin B

Steyn, Pieter S.,Payne, Barry E.

, p. 69 - 70 (2007/10/03)

The effective synthesis of bromo- and iodo-ochratoxin B by the treatment of ochratoxin B with pyridinium hydrobromide perbromide, and iodine and mercury(II)oxide, respectively, is reported.
