Check Digit Verification of cas no
The CAS Registry Mumber 42808-05-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,8,0 and 8 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 42808-05:
(7*4)+(6*2)+(5*8)+(4*0)+(3*8)+(2*0)+(1*5)=109
109 % 10 = 9
So 42808-05-9 is a valid CAS Registry Number.

Tyrosinase plays a key role in melanin formation, and it is closely related to hyper pigmentation in animals and enzymatic browning in food. Thus, it is of great significance to screen inhibitors of tyrosinase. In this work, a new chiral ligand exchange-capillary electrophoresis (CLE-CE) system based on the coordination effect of Zn(ii)-l-leucine complexes and β-cyclodextrin (β-CD) was developed for screening the inhibitors of tyrosinase. The effects of the concentration of β-CD, buffer pH, the ratio of l-leucine to Zn(ii), and the complex concentration were investigated with Dns-d,l-tyrosine, Dns-d,l-valine and Dns-d,l-phenylalanine as the tested analytes. The optimum buffer conditions were composed of 100.0 mM boric acid, 5.0 mM ammonium acetate, 3.0 mM Zn(ii), 6.0 mM l-leucine and 4.0 mM β-CD at pH 8.2. It has been found that six pairs of Dns-d,l-AAs could be baseline-separated and five pairs of Dns-d,l-AAs were partly enantioseparated. Then the quantitative analysis of l-tyrosine was conducted and good linearity (r2 = 0.992) was obtained with a concentration ranging from 12.95 μM to 413.3 μM. A kinetics study of tyrosinase was realized, and the Km and Vmax were 636 μM and 312 μmol min-1 mg-1. Moreover, the proposed method was applied in screening the inhibitors of tyrosinase with four kinds of chalcones as the model inhibitors. The results demonstrated that the developed CLE-CE system was favorable for screening enzyme inhibitors, and showed great potential in related drugs discovery and clinical analysis in the future.
