117896-34-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 117896-34-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,8,9 and 6 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 117896-34:
(8*1)+(7*1)+(6*7)+(5*8)+(4*9)+(3*6)+(2*3)+(1*4)=161
161 % 10 = 1
So 117896-34-1 is a valid CAS Registry Number.

Threefold and chemoselective couplings of triarylbismuths with benzylic chlorides and iodides using palladium catalysis

Rao, Maddali L. N.,Dhanorkar, Ritesh J.

, p. 13134 - 13144 (2014/04/03)

This paper describes the palladium-catalyzed studies on threefold coupling of triarylbismuth reagents with benzylic chlorides and iodides. The optimized protocol conditions are operationally simple, delivering threefold coupling of a variety of triarylbismuths in combination with benzylic chlorides and iodides. The two optimized protocols allowed the synthesis of a diverse range of unsymmetrical diarylmethanes in an efficient manner. As part of this study, chemoselective transformation of benzylic chlorides and iodides was also achieved. This journal is the Partner Organisations 2014.
