Check Digit Verification of cas no

The CAS Registry Mumber 228262-89-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,8,2,6 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 228262-89:
(8*2)+(7*2)+(6*8)+(5*2)+(4*6)+(3*2)+(2*8)+(1*9)=143
143 % 10 = 3
So 228262-89-3 is a valid CAS Registry Number.

N-heterocyclic carbene-palladium(II)-1-methylimidazole complex catalyzed Mizoroki-Heck reaction of aryl chlorides with styrenes

Gao, Ting-Ting,Jin, Ai-Ping,Shao, Li-Xiong

, p. 1916 - 1919 (2012)

A well-defined N-heterocyclic carbene-palladium(II)-1-methylimidazole [NHC-Pd(II)-Im] complex 1 was found to be an effective catalyst for the Mizoroki-Heck reaction of a variety of aryl chlorides with styrenes. Both activated and deactivated aryl chlorides work well to give the corresponding coupling products in good to excellent yields by using tetrabutylammonium bromide (TBAB) as the ionic liquid.
