218898-28-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 218898-28-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,8,8,9 and 8 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 218898-28:
(8*2)+(7*1)+(6*8)+(5*8)+(4*9)+(3*8)+(2*2)+(1*8)=183
183 % 10 = 3
So 218898-28-3 is a valid CAS Registry Number.
