Check Digit Verification of cas no

The CAS Registry Mumber 6680-38-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,8 and 0 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 6680-38:
(6*6)+(5*6)+(4*8)+(3*0)+(2*3)+(1*8)=112
112 % 10 = 2
So 6680-38-2 is a valid CAS Registry Number.
