Check Digit Verification of cas no
The CAS Registry Mumber 53921-04-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,9,2 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 53921-04:
(7*5)+(6*3)+(5*9)+(4*2)+(3*1)+(2*0)+(1*4)=113
113 % 10 = 3
So 53921-04-3 is a valid CAS Registry Number.

Acetylhydrazine, semicarbazide and methoxycarbonylhydrazine react with β-aminoenones to give regioselectively the corresponding N-acetyl- or N- carboxypyrazole derivatives. The reaction are highly regioselective and occurs via 5-hydroxypyrazolines which in several case can be isolated and characterized.
