128886-99-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 128886-99-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,8,8 and 6 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 128886-99:
(8*1)+(7*2)+(6*8)+(5*8)+(4*8)+(3*6)+(2*9)+(1*9)=187
187 % 10 = 7
So 128886-99-7 is a valid CAS Registry Number.
