89128-39-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89128-39-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,1,2 and 8 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 89128-39:
(7*8)+(6*9)+(5*1)+(4*2)+(3*8)+(2*3)+(1*9)=162
162 % 10 = 2
So 89128-39-2 is a valid CAS Registry Number.
