Check Digit Verification of cas no
The CAS Registry Mumber 28817-28-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,8,1 and 7 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 28817-28:
(7*2)+(6*8)+(5*8)+(4*1)+(3*7)+(2*2)+(1*8)=139
139 % 10 = 9
So 28817-28-9 is a valid CAS Registry Number.
