Check Digit Verification of cas no
The CAS Registry Mumber 111888-03-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,8,8 and 8 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 111888-03:
(8*1)+(7*1)+(6*1)+(5*8)+(4*8)+(3*8)+(2*0)+(1*3)=120
120 % 10 = 0
So 111888-03-0 is a valid CAS Registry Number.
