89265-25-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89265-25-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,2,6 and 5 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 89265-25:
(7*8)+(6*9)+(5*2)+(4*6)+(3*5)+(2*2)+(1*5)=168
168 % 10 = 8
So 89265-25-8 is a valid CAS Registry Number.
