89581-41-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 89581-41-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,5,8 and 1 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 89581-41:
(7*8)+(6*9)+(5*5)+(4*8)+(3*1)+(2*4)+(1*1)=179
179 % 10 = 9
So 89581-41-9 is a valid CAS Registry Number.
