Check Digit Verification of cas no
The CAS Registry Mumber 28520-18-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,5,2 and 0 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 28520-18:
(7*2)+(6*8)+(5*5)+(4*2)+(3*0)+(2*1)+(1*8)=105
105 % 10 = 5
So 28520-18-5 is a valid CAS Registry Number.

Arylacetaldehydes were successfully synthesized by the anti-Markovnikov Wacker-type oxidation of vinylarenes using 1 atm O2 as a terminal oxidant under mild conditions. Electron-deficient alkenes, such as maleic anhydride and maleimides, were effective additives and would operate as ligands to stabilize the Pd(0) species during the reaction.
