Check Digit Verification of cas no

The CAS Registry Mumber 874989-66-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,4,9,8 and 9 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 874989-66:
(8*8)+(7*7)+(6*4)+(5*9)+(4*8)+(3*9)+(2*6)+(1*6)=259
259 % 10 = 9
So 874989-66-9 is a valid CAS Registry Number.
