Check Digit Verification of cas no

The CAS Registry Mumber 1518-15-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,1 and 8 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1518-15:
(6*1)+(5*5)+(4*1)+(3*8)+(2*1)+(1*5)=66
66 % 10 = 6
So 1518-15-6 is a valid CAS Registry Number.
