Check Digit Verification of cas no
The CAS Registry Mumber 139113-01-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,1,1 and 3 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 139113-01:
(8*1)+(7*3)+(6*9)+(5*1)+(4*1)+(3*3)+(2*0)+(1*1)=102
102 % 10 = 2
So 139113-01-2 is a valid CAS Registry Number.
