Check Digit Verification of cas no

The CAS Registry Mumber 158149-98-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,1,4 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 158149-98:
(8*1)+(7*5)+(6*8)+(5*1)+(4*4)+(3*9)+(2*9)+(1*8)=165
165 % 10 = 5
So 158149-98-5 is a valid CAS Registry Number.
