Check Digit Verification of cas no
The CAS Registry Mumber 111203-08-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,2,0 and 3 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 111203-08:
(8*1)+(7*1)+(6*1)+(5*2)+(4*0)+(3*3)+(2*0)+(1*8)=48
48 % 10 = 8
So 111203-08-8 is a valid CAS Registry Number.
