890028-20-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 890028-20-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,0,0,2 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 890028-20:
(8*8)+(7*9)+(6*0)+(5*0)+(4*2)+(3*8)+(2*2)+(1*0)=163
163 % 10 = 3
So 890028-20-3 is a valid CAS Registry Number.
