The CAS Registry Mumber 195967-09-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,5,9,6 and 7 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 195967-09:
(8*1)+(7*9)+(6*5)+(5*9)+(4*6)+(3*7)+(2*0)+(1*9)=200
200 % 10 = 0

Novel synthesis of substituted 4′-hydroxy-2,2′:6′,2″-terpyridines
Fallahpour, Reza-Ali,Constable, Edwin C.
, p. 2263 - 2264 (1997)
4-Substituted-2,6-diacetylpyridines 2-4 have been synthesised; by using the Kroehnke-methodology, chalcone and methylacylpyridinium salts have been reacted to yield 4′-ethoxy-2,2′:6′,2″-terpyridines 5-7. These novel 2,2′:6′,2″-terpyridines are functionali
