157606-35-4 Usage
Uses
Okadaic Acid 9-Anthrylmethyl Ester is a standard useful in the analysis of okadaic acid (CAT# O515500), which is a widely distributed marine toxin produced by several phytoplanktonic species and a potent and specific inhibitor of various types of serine/threonine protein phosphatases.
Check Digit Verification of cas no
The CAS Registry Mumber 157606-35-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,6,0 and 6 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 157606-35:
(8*1)+(7*5)+(6*7)+(5*6)+(4*0)+(3*6)+(2*3)+(1*5)=144
144 % 10 = 4
So 157606-35-4 is a valid CAS Registry Number.

Fluorometric Determination of Diarrhetic Shellfish Toxins by High-Performance Liquid Chromatography
Lee, Jong Soo,Yanagi, Toshihiko,Kenma, Ritsuko,Yasumoto, Takeshi
, p. 877 - 882 (2007/10/02)
Two principal toxins of diarrhetic shellfish poisoning, okadaic acid and dinophysistoxin-1, were esterified with 9-anthryldiazomethane in methanol.After cleaning with a Sep-pak silica cartridge column, the fluorescent esters were analyzed on a Develosil ODS column with MeCN-MeOH-H2O (8:1:1).The fluorescence intensities of both toxin derivatives measured at an excitation of 365 nm and an emission of 412 nm showed good linearity in the range 1 ca. 80 ng.
