128504-29-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128504-29-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,5,0 and 4 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 128504-29:
(8*1)+(7*2)+(6*8)+(5*5)+(4*0)+(3*4)+(2*2)+(1*9)=120
120 % 10 = 0
So 128504-29-0 is a valid CAS Registry Number.
