Check Digit Verification of cas no
The CAS Registry Mumber 28118-54-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,1,1 and 8 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 28118-54:
(7*2)+(6*8)+(5*1)+(4*1)+(3*8)+(2*5)+(1*4)=109
109 % 10 = 9
So 28118-54-9 is a valid CAS Registry Number.
