Check Digit Verification of cas no
The CAS Registry Mumber 525-05-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,2 and 5 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 525-05:
(5*5)+(4*2)+(3*5)+(2*0)+(1*5)=53
53 % 10 = 3
So 525-05-3 is a valid CAS Registry Number.
