Check Digit Verification of cas no
The CAS Registry Mumber 139112-73-5 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 2 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 139112-73:
(8*1)+(7*3)+(6*9)+(5*1)+(4*1)+(3*2)+(2*7)+(1*3)=115
115 % 10 = 5
