86990-80-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 86990-80-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,9,9 and 0 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 86990-80:
(7*8)+(6*6)+(5*9)+(4*9)+(3*0)+(2*8)+(1*0)=189
189 % 10 = 9
So 86990-80-9 is a valid CAS Registry Number.
