Check Digit Verification of cas no

The CAS Registry Mumber 5660-82-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,6 and 0 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 5660-82:
(6*5)+(5*6)+(4*6)+(3*0)+(2*8)+(1*2)=102
102 % 10 = 2
So 5660-82-2 is a valid CAS Registry Number.
