Check Digit Verification of cas no
The CAS Registry Mumber 3771-14-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,7 and 1 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 3771-14:
(6*3)+(5*7)+(4*7)+(3*1)+(2*1)+(1*4)=90
90 % 10 = 0
So 3771-14-0 is a valid CAS Registry Number.

A chromogenic substrate for solid-phase detection of phospholipase A 2

, p. 43 - 45 (2014)
A method for solid-phase detection of phospholipase A2 (PLA 2) was developed. The method uses 1-octanoyloxynaphthalene-3-sulfonic acid, which was found to be a good substrate of PLA2. The substrate is hydrolyzed by PLA2 into 1-naphthol-3-sulfonic acid, which is spontaneously coupled with coexisting diazonium salt to form a red-purple azo dye. Streptomyces and bovine pancreatic PLA2 spotted on a nitrocellulose membrane could be detected by this method with considerable sensitivity. In addition, colonies of recombinant Escherichia coli producing bacterial PLA2 were distinguishable from those producing an inactive mutant PLA2, facilitating high-throughput screening in directed evolution of the enzyme.
