81016-05-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81016-05-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,0,1 and 6 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 81016-05:
(7*8)+(6*1)+(5*0)+(4*1)+(3*6)+(2*0)+(1*5)=89
89 % 10 = 9
So 81016-05-9 is a valid CAS Registry Number.
