Check Digit Verification of cas no
The CAS Registry Mumber 118533-10-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,5,3 and 3 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 118533-10:
(8*1)+(7*1)+(6*8)+(5*5)+(4*3)+(3*3)+(2*1)+(1*0)=111
111 % 10 = 1
So 118533-10-1 is a valid CAS Registry Number.
