180720-86-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 180720-86-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,7,2 and 0 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 180720-86:
(8*1)+(7*8)+(6*0)+(5*7)+(4*2)+(3*0)+(2*8)+(1*6)=129
129 % 10 = 9
So 180720-86-9 is a valid CAS Registry Number.
