128019-80-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 128019-80-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,0,1 and 9 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 128019-80:
(8*1)+(7*2)+(6*8)+(5*0)+(4*1)+(3*9)+(2*8)+(1*0)=117
117 % 10 = 7
So 128019-80-7 is a valid CAS Registry Number.
