89045-25-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89045-25-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,0,4 and 5 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 89045-25:
(7*8)+(6*9)+(5*0)+(4*4)+(3*5)+(2*2)+(1*5)=150
150 % 10 = 0
So 89045-25-0 is a valid CAS Registry Number.
