Check Digit Verification of cas no
The CAS Registry Mumber 28221-89-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,2,2 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 28221-89:
(7*2)+(6*8)+(5*2)+(4*2)+(3*1)+(2*8)+(1*9)=108
108 % 10 = 8
So 28221-89-8 is a valid CAS Registry Number.
