Check Digit Verification of cas no

The CAS Registry Mumber 1988-78-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,8 and 8 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1988-78:
(6*1)+(5*9)+(4*8)+(3*8)+(2*7)+(1*8)=129
129 % 10 = 9
So 1988-78-9 is a valid CAS Registry Number.

An efficient and selective hydroarylation of styrenes with electron-rich arenes, catalyzed by bismuth(III) chloride and affording Markovnikov adducts

Sun, Hong-Bin,Li, Biao,Hua, Ruimao,Yin, Gwu

, p. 4231 - 4236 (2006)

In the presence of BiCl3, the hydroarylation of styrenes with electron-rich arenes afforded Markovnikov adducts selectively in good to high yields. Under arene-free conditions, the intermolecular hydroarylation of α-substituted styrenes and subsequent intramolecular hydroarylation produced the cyclic dimers of α-substituted styrenes in good yields. Wiley-VCH Verlag GmbH & Co. KGaA, 2006.
