Check Digit Verification of cas no
The CAS Registry Mumber 139313-35-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,3,1 and 3 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 139313-35:
(8*1)+(7*3)+(6*9)+(5*3)+(4*1)+(3*3)+(2*3)+(1*5)=122
122 % 10 = 2
So 139313-35-2 is a valid CAS Registry Number.
