173463-59-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 173463-59-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,4,6 and 3 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 173463-59:
(8*1)+(7*7)+(6*3)+(5*4)+(4*6)+(3*3)+(2*5)+(1*9)=147
147 % 10 = 7
So 173463-59-7 is a valid CAS Registry Number.

CONVENIENT SYNTHESIS OF CYCLOALKENE-FUSED PHTHALAZINONES
Haider, Norbert
, p. 2519 - 2526 (2007/10/03)
A series cycloalkene-annelated phthalazin-1(2H)-ones (2-5) was prepared in high yields by a one pot procedure, employing pyridazinopyridazin-1(2H)-ones (1) as azadienes and cyclic enamines as dienophiles in an inverse-electron-demand Diels-Alder reaction, followed by acid catalyzed aromatization.
