Check Digit Verification of cas no

The CAS Registry Mumber 436850-13-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,6,8,5 and 0 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 436850-13:
(8*4)+(7*3)+(6*6)+(5*8)+(4*5)+(3*0)+(2*1)+(1*3)=154
154 % 10 = 4
So 436850-13-4 is a valid CAS Registry Number.

Synthesis of new pyridazin-6-ones, pyridazin-6-imines, 4-pyridazinals, and pyridines

Sayed, Samia M.,Khalil, Mohamed A.,Ahmed, Maghraby A.,Raslan, Mohamed A.

, p. 481 - 495 (2007/10/03)

3-Dimethyl-1-[3-methyl-(4H)-5-phenylimidazol[2,1-b]thiazol-2-yl]prop-2-enone 4 couples smoothly with benzenediazonium chloride to yield propanal 5 which is a key intermediate for the synthesis of pyridazinones 9-13, 16 and pyridazine-6-imine 8, 19. Pentadienonitrile 18 was converted into pyridine-3-carbonitrile 20 on refluxing in ethanolic sodium ethoxide solution. Pyrazole 24 was synthesized from the reaction of 5 with 1-chloro-2-phenylhydrazono propan-2-one 22.
