Check Digit Verification of cas no

The CAS Registry Mumber 165058-04-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,5,0,5 and 8 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 165058-04:
(8*1)+(7*6)+(6*5)+(5*0)+(4*5)+(3*8)+(2*0)+(1*4)=128
128 % 10 = 8
So 165058-04-8 is a valid CAS Registry Number.
