Check Digit Verification of cas no

The CAS Registry Mumber 4590-87-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,9 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4590-87:
(6*4)+(5*5)+(4*9)+(3*0)+(2*8)+(1*7)=108
108 % 10 = 8
So 4590-87-8 is a valid CAS Registry Number.
