Check Digit Verification of cas no
The CAS Registry Mumber 220381-78-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,3,8 and 1 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 220381-78:
(8*2)+(7*2)+(6*0)+(5*3)+(4*8)+(3*1)+(2*7)+(1*8)=102
102 % 10 = 2
So 220381-78-2 is a valid CAS Registry Number.

, p. 1461 - 1463 (1999)
The title compound, [PdI(C5H3ClN){P(C6H5) 3}2], a key intermediate in the palladium-catalysed coupling of two aryl rings, has been isolated and shown to have a square-planar structure with the iodo and 6-chloropyridin-2-yl ligands in trans positions.
