Check Digit Verification of cas no

The CAS Registry Mumber 179989-98-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,9,9,8 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 179989-98:
(8*1)+(7*7)+(6*9)+(5*9)+(4*8)+(3*9)+(2*9)+(1*8)=241
241 % 10 = 1
So 179989-98-1 is a valid CAS Registry Number.
