Check Digit Verification of cas no
The CAS Registry Mumber 5653-98-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,5 and 3 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 5653-98:
(6*5)+(5*6)+(4*5)+(3*3)+(2*9)+(1*8)=115
115 % 10 = 5
So 5653-98-5 is a valid CAS Registry Number.

Direct alkylation of pyridazines and related compounds by organolithium reagents
Piaz, Vittorio Dal,Capperucci, Antonella
, p. 762 - 764 (2007/10/03)
Reaction of chloropyridazines with lithium reagents afforded the corresponding 4(5)-alkylated 1,2-diazines, while treatment of 3(2H)-pyridazinones gave predominantly 4-alkylated-4,5-dihydro compounds.
