Check Digit Verification of cas no

The CAS Registry Mumber 118618-98-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,6,1 and 8 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 118618-98:
(8*1)+(7*1)+(6*8)+(5*6)+(4*1)+(3*8)+(2*9)+(1*8)=147
147 % 10 = 7
So 118618-98-7 is a valid CAS Registry Number.
