128309-69-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128309-69-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,3,0 and 9 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 128309-69:
(8*1)+(7*2)+(6*8)+(5*3)+(4*0)+(3*9)+(2*6)+(1*9)=133
133 % 10 = 3
So 128309-69-3 is a valid CAS Registry Number.
