89368-25-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89368-25-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,3,6 and 8 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 89368-25:
(7*8)+(6*9)+(5*3)+(4*6)+(3*8)+(2*2)+(1*5)=182
182 % 10 = 2
So 89368-25-2 is a valid CAS Registry Number.
