128640-75-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128640-75-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,6,4 and 0 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 128640-75:
(8*1)+(7*2)+(6*8)+(5*6)+(4*4)+(3*0)+(2*7)+(1*5)=135
135 % 10 = 5
So 128640-75-5 is a valid CAS Registry Number.
