Check Digit Verification of cas no
The CAS Registry Mumber 111223-13-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,2,2 and 3 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 111223-13:
(8*1)+(7*1)+(6*1)+(5*2)+(4*2)+(3*3)+(2*1)+(1*3)=53
53 % 10 = 3
So 111223-13-3 is a valid CAS Registry Number.
