83323-25-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83323-25-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,3,2 and 3 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 83323-25:
(7*8)+(6*3)+(5*3)+(4*2)+(3*3)+(2*2)+(1*5)=115
115 % 10 = 5
So 83323-25-5 is a valid CAS Registry Number.
