28688-23-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 28688-23-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,6,8 and 8 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 28688-23:
(7*2)+(6*8)+(5*6)+(4*8)+(3*8)+(2*2)+(1*3)=155
155 % 10 = 5
So 28688-23-5 is a valid CAS Registry Number.

THALLIUM IN ORGANIC SYNTHESIS. XLIV. ELECTROPHILIC THALLATION OF ELECTRON-RICH ARENES
Taylor, Edward C.,Katz, Alan H.,Alvarado, Sergio I.,McKillop, Alexander
, p. C9 - C12 (2007/10/02)
Electron-rich arenes, which normally undergo oxidative coupling to biaryls with TTFA/TFA, can be smoothly thallated in high yield with TTFA in a 1/1 mixture of TTFA and ether.
