87016-16-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87016-16-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,0,1 and 6 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 87016-16:
(7*8)+(6*7)+(5*0)+(4*1)+(3*6)+(2*1)+(1*6)=128
128 % 10 = 8
So 87016-16-8 is a valid CAS Registry Number.
