Check Digit Verification of cas no
The CAS Registry Mumber 192643-83-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,2,6,4 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 192643-83:
(8*1)+(7*9)+(6*2)+(5*6)+(4*4)+(3*3)+(2*8)+(1*3)=157
157 % 10 = 7
So 192643-83-7 is a valid CAS Registry Number.

Heteroaryl halides undergoes cross-couplings with alkynes in good yields in the presence of [PdCl(C3H5)]2/cis,cis,cis-1,2, 3,4-tetrakis(diphenylphosphinomethyl)cyclopentane as catalyst. A variety of heteroaryl halides such as pyridines, quinolines, a pyrimidine, an indole, a thiophene, or a thiazole have been used successfully. The reaction also tolerates several alkynes such as phenylacetylene and a range of alk-1-ynols. Furthermore, this catalyst can be used at low loading with some substrates.
