139220-20-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 139220-20-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,2,2 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 139220-20:
(8*1)+(7*3)+(6*9)+(5*2)+(4*2)+(3*0)+(2*2)+(1*0)=105
105 % 10 = 5
So 139220-20-5 is a valid CAS Registry Number.
