128589-63-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128589-63-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,5,8 and 9 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 128589-63:
(8*1)+(7*2)+(6*8)+(5*5)+(4*8)+(3*9)+(2*6)+(1*3)=169
169 % 10 = 9
So 128589-63-9 is a valid CAS Registry Number.
