Check Digit Verification of cas no
The CAS Registry Mumber 40175-80-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,1,7 and 5 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 40175-80:
(7*4)+(6*0)+(5*1)+(4*7)+(3*5)+(2*8)+(1*0)=92
92 % 10 = 2
So 40175-80-2 is a valid CAS Registry Number.

Direct functionalization of 4,5-dichloropyridazin-6-one with some nucleophiles in seven solvents gave regioselectively 5-halo- 4-substituted-pyridazin-6-ones as main product. Reaction of 4,5- dichloropyridazin-6-one with 2-mercaptopyrimidine (2 equivalents) also afforded 4,5-di(pyrimidin-2-ylsulfanyl)pyridazin-6-one as the main product.
