Check Digit Verification of cas no
The CAS Registry Mumber 163085-40-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,3,0,8 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 163085-40:
(8*1)+(7*6)+(6*3)+(5*0)+(4*8)+(3*5)+(2*4)+(1*0)=123
123 % 10 = 3
So 163085-40-3 is a valid CAS Registry Number.

SYNTHESIS OF CERTAIN DIPYRIDYLACETYLENES USING PALLADIUM-CATALYZED CROSS-COUPLING OF ETHYNYL- AND HALOPYRIDINES
Karchava, A. V.,Maksimova, F. V.,Yurovskaya, M. A.
, p. 1195 - 1199 (1994)
A series of dipyridylacetylenes were obtained by reacting ethynylpyridines with chloro- and bromopyridines during catalysis with phosphino complexes of palladium in the presence of copper iodide and a base.
