Check Digit Verification of cas no
The CAS Registry Mumber 113966-96-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,9,6 and 6 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 113966-96:
(8*1)+(7*1)+(6*3)+(5*9)+(4*6)+(3*6)+(2*9)+(1*6)=144
144 % 10 = 4
So 113966-96-4 is a valid CAS Registry Number.
