Check Digit Verification of cas no

The CAS Registry Mumber 1293326-49-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,3,3,2 and 6 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1293326-49:
(9*1)+(8*2)+(7*9)+(6*3)+(5*3)+(4*2)+(3*6)+(2*4)+(1*9)=164
164 % 10 = 4
So 1293326-49-4 is a valid CAS Registry Number.

2,6-Bis(phenylethynyl)biphenyls and their cyclization to pyrenes

MacHuy, Mareike M.,Wuertele, Christian,Schreiner, Peter R.

experimental part, p. 1405 - 1409 (2012/07/02)

We present a new protocol for pyrene synthesis via transition-metal cross-couplings. The initially prepared 2,6-bis(phenylethynyl)biphenyls were transformed to pyrenes with uncommon 4,10-disubstitution through an electrophilic cyclization. The precursors were synthesized by Suzuki-Miyaura cross-coupling, which provides 2,6-dibromobiphenyls; these were subsequently coupled with phenylethynyl derivatives via Kumada cross-coupling.
