Check Digit Verification of cas no

The CAS Registry Mumber 4980-15-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,8 and 0 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4980-15:
(6*4)+(5*9)+(4*8)+(3*0)+(2*1)+(1*5)=108
108 % 10 = 8
So 4980-15-8 is a valid CAS Registry Number.
