50567-35-6 Usage
Definition
ChEBI: A pyrazole that is antiipyrine substituted at C-4 by a methyl(sulfomethyl)amino group, the sodium salt of which, metamizole sodium, was widely used as a powerful analgesic and antipyretic, but withdrawn from many markets from the 1970s due to a risk of cau
ing risk of causing agranulocytosis.
Check Digit Verification of cas no
The CAS Registry Mumber 50567-35-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,5,6 and 7 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 50567-35:
(7*5)+(6*0)+(5*5)+(4*6)+(3*7)+(2*3)+(1*5)=116
116 % 10 = 6
So 50567-35-6 is a valid CAS Registry Number.
