Check Digit Verification of cas no
The CAS Registry Mumber 82325-23-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,3,2 and 5 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 82325-23:
(7*8)+(6*2)+(5*3)+(4*2)+(3*5)+(2*2)+(1*3)=113
113 % 10 = 3
So 82325-23-3 is a valid CAS Registry Number.
