108643-85-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 108643-85-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,6,4 and 3 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 108643-85:
(8*1)+(7*0)+(6*8)+(5*6)+(4*4)+(3*3)+(2*8)+(1*5)=132
132 % 10 = 2
So 108643-85-2 is a valid CAS Registry Number.

Trimethylsilyl Chloride/Tetramethylethylenediamine Facilitated Additions of Organocopper Reagents (RCu) to Enones
Johnson, Carl R.,Marren, Thomas J.
, p. 27 - 30 (2007/10/02)
Alkylcoppers (RCu) add readily in a conjugate fashion to enones in the presence of TMSCl and TMEDA to give high yields of trimethylsilyl enol ethers.
