81459-00-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81459-00-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,4,5 and 9 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 81459-00:
(7*8)+(6*1)+(5*4)+(4*5)+(3*9)+(2*0)+(1*0)=129
129 % 10 = 9
So 81459-00-9 is a valid CAS Registry Number.
