Check Digit Verification of cas no

The CAS Registry Mumber 56605-80-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,6,0 and 5 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 56605-80:
(7*5)+(6*6)+(5*6)+(4*0)+(3*5)+(2*8)+(1*0)=132
132 % 10 = 2
So 56605-80-2 is a valid CAS Registry Number.
