Check Digit Verification of cas no
The CAS Registry Mumber 17763-95-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,7,6 and 3 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 17763-95:
(7*1)+(6*7)+(5*7)+(4*6)+(3*3)+(2*9)+(1*5)=140
140 % 10 = 0
So 17763-95-0 is a valid CAS Registry Number.

A site-selective and stereospecific cascade Suzuki-Miyaura annulation of alkyl 1,2-bisboronic esters and 2,2′-dihalo 1,1′-biaryls
Willems, Suzanne,Toupalas, Georgios,Reisenbauer, Julia C.,Morandi, Bill

A cascade Suzuki-Miyaura cross-coupling giving rise to 9,10-dihydrophenanthrenes has been developed. Using biaryls with unsymmetrical substitution-pattern full site-selectivity was observed. Furthermore, this cross-coupling of an alkyl 1,2-bisboronic pinacol ester proceeds through the challenging coupling of a secondary boronate with complete stereoretention.

A chiral dirhodium(II) paddlewheel complex has been synthesized from biscarboxylate ligands derived from BINOL, and the resulting complex has been used in enantioselective carbene/alkyne cascade reactions. The ligand design was guided by requirements of α
Efficient synthesis of biscarbazoles by palladium-catalyzed twofold C-N coupling and C-H activation reactions

A new and efficient strategy for the synthesis of 3,9′- and 2,9′-biscarbazoles was developed. Our strategy relies on the cyclization of 1,1′-biphenyl-2,2′-diyl bis(trifluoromethanesulfonate) with 4- or 3-anisidine, transformation of the methoxy to a triflate group and subsequent oxidative Pd-catalyzed cyclization with various anilines.
