139871-31-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 139871-31-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,8,7 and 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 139871-31:
(8*1)+(7*3)+(6*9)+(5*8)+(4*7)+(3*1)+(2*3)+(1*1)=161
161 % 10 = 1
So 139871-31-1 is a valid CAS Registry Number.
