Check Digit Verification of cas no

The CAS Registry Mumber 56520-91-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,5,2 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 56520-91:
(7*5)+(6*6)+(5*5)+(4*2)+(3*0)+(2*9)+(1*1)=123
123 % 10 = 3
So 56520-91-3 is a valid CAS Registry Number.
