128432-39-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128432-39-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,4,3 and 2 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 128432-39:
(8*1)+(7*2)+(6*8)+(5*4)+(4*3)+(3*2)+(2*3)+(1*9)=123
123 % 10 = 3
So 128432-39-3 is a valid CAS Registry Number.
