128765-68-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128765-68-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,7,6 and 5 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 128765-68:
(8*1)+(7*2)+(6*8)+(5*7)+(4*6)+(3*5)+(2*6)+(1*8)=164
164 % 10 = 4
So 128765-68-4 is a valid CAS Registry Number.
