Check Digit Verification of cas no
The CAS Registry Mumber 28469-92-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,4,6 and 9 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 28469-92:
(7*2)+(6*8)+(5*4)+(4*6)+(3*9)+(2*9)+(1*2)=153
153 % 10 = 3
So 28469-92-3 is a valid CAS Registry Number.

Low pressure vinylation of aryl and vinyl halides via Heck-Mizoroki reactions using ethylene
Smith, Craig R.,RajanBabu
supporting information; experimental part, p. 1102 - 1110 (2010/03/25)
Aryl bromides and iodides in the presence of catalytic amounts of a palladacycle derived from acetophenone oxime and 2 equiv of potassium acetate react with ethylene under ambient pressure (15-30 psi) to give the corresponding vinylarenes. The reactions work with both electron-deficient and electron-rich aryl compounds and tolerate wide variety of common functional groups. Vinyl bromides lead to 1,3-dienes in moderate yields.
