Uses
6-Methyl-2,3,4,5-tetrahydropyridazin-3-one (cas# 5157-08-4) is a useful research chemical.
Check Digit Verification of cas no
The CAS Registry Mumber 5157-08-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,5 and 7 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 5157-08:
(6*5)+(5*1)+(4*5)+(3*7)+(2*0)+(1*8)=84
84 % 10 = 4
So 5157-08-4 is a valid CAS Registry Number.
