Check Digit Verification of cas no
The CAS Registry Mumber 127806-49-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,8,0 and 6 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 127806-49:
(8*1)+(7*2)+(6*7)+(5*8)+(4*0)+(3*6)+(2*4)+(1*9)=139
139 % 10 = 9
So 127806-49-9 is a valid CAS Registry Number.

Synthesis and pharmacology of 3-aryl-5,6-dihydro-6-oxo-1(4H)-pyridazineacetic acid derivatives
Kane,Huber,Miller,Kehne
, p. 249 - 251 (2007/10/02)
The title compounds were prepared by alkylation of 6-aryl-4,5-dihydro-3(2H)-pyridazinones with esters of α-bromoacetic acid. Hydrolysis of these esters afforded the corresponding carboxylic acids which were coupled with various amines yielding 6-oxo-1(4H)
