Check Digit Verification of cas no
The CAS Registry Mumber 25974-26-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,9,7 and 4 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 25974-26:
(7*2)+(6*5)+(5*9)+(4*7)+(3*4)+(2*2)+(1*6)=139
139 % 10 = 9
So 25974-26-9 is a valid CAS Registry Number.

Synthesis of N,N-Dioxopyridazines

Despite many efforts, one of the smallest heterocycles containing two nitrogen atoms, pyridazine, could not be converted to its N,N-dioxide (see, however, Nakadate et al. Chem. Pharm. Bull. 1970, 18, 1211-1218). HOF·CH3CN, made easily from diluted fluorine, was able to accomplish this task in a fast reaction with good yields.
