89005-24-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89005-24-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,0,0 and 5 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 89005-24:
(7*8)+(6*9)+(5*0)+(4*0)+(3*5)+(2*2)+(1*4)=133
133 % 10 = 3
So 89005-24-3 is a valid CAS Registry Number.
