Check Digit Verification of cas no
The CAS Registry Mumber 87544-94-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,5,4 and 4 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 87544-94:
(7*8)+(6*7)+(5*5)+(4*4)+(3*4)+(2*9)+(1*4)=173
173 % 10 = 3
So 87544-94-3 is a valid CAS Registry Number.

PYRIDAZINES CONDENSED WITH A HETERO RING, II. PYRIDO AMINOPYRIDAZINES, I. SEPARATION AND STRUCTURE DETERMINATION OF THE ISOMERIC MONOCHLORO COMPOUNDS OBTAINED BY HYDROLYSIS OF 1,4-DICHLOROPYRIDOPYRIDAZINE

, p. 487 - 500 (2007/10/02)
The separation of the mixture of isomers 2 and 3, obtained by hydrolysis of 1,4-dichloropyrido pyridazine, was accomplished and the structures of the isomers (2: 1-Cl; 3:4-Cl) were verified by synthesis.Aminolysis of 2 and 3 yielded the hydroxy-ethylamino derivatives 4 and 5; a mixture of these compounds can also be synthesized from 2-tosyloxyethylcinchomeronic imide (20 -> 4, 5) in a good yield (84percent).
