Check Digit Verification of cas no

The CAS Registry Mumber 121582-85-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,5,8 and 2 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 121582-85:
(8*1)+(7*2)+(6*1)+(5*5)+(4*8)+(3*2)+(2*8)+(1*5)=112
112 % 10 = 2
So 121582-85-2 is a valid CAS Registry Number.

Pyridazines with Heteroatom Substituents in Position 3 and 5. 3) 2-Aryl-5-hydroxypyridazin-3(2H)-ones as Potential Herbicides: Synthesis and Some Reactions

Schober, Bernt D.,Megyeri, Gabor,Kappe, Thomas

, p. 169 - 176 (2007/10/02)

The coupling of dimethyl acetonedicarboxylate 1 with a variety of aryldiazonium salts 2a-i produces the hydrazones 3a-i which can be cyclized in boiling dichlorobenzene to yield the pyridazone esters 4a-i, or in sodium hydroxide solution to give the pyrid
