Check Digit Verification of cas no
The CAS Registry Mumber 566-61-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,6 and 6 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 566-61:
(5*5)+(4*6)+(3*6)+(2*6)+(1*1)=80
80 % 10 = 0
So 566-61-0 is a valid CAS Registry Number.
