128980-94-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128980-94-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,9,8 and 0 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 128980-94:
(8*1)+(7*2)+(6*8)+(5*9)+(4*8)+(3*0)+(2*9)+(1*4)=169
169 % 10 = 9
So 128980-94-9 is a valid CAS Registry Number.
