128569-57-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128569-57-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,5,6 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 128569-57:
(8*1)+(7*2)+(6*8)+(5*5)+(4*6)+(3*9)+(2*5)+(1*7)=163
163 % 10 = 3
So 128569-57-3 is a valid CAS Registry Number.
