247576-52-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 247576-52-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,7,5,7 and 6 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 247576-52:
(8*2)+(7*4)+(6*7)+(5*5)+(4*7)+(3*6)+(2*5)+(1*2)=169
169 % 10 = 9
So 247576-52-9 is a valid CAS Registry Number.

Novel synthesis of substituted 4′-hydroxy-2,2′:6′,2″-terpyridines
Fallahpour, Reza-Ali,Constable, Edwin C.
, p. 2263 - 2264 (2007/10/03)
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
