Check Digit Verification of cas no

The CAS Registry Mumber 404597-92-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,4,5,9 and 7 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 404597-92:
(8*4)+(7*0)+(6*4)+(5*5)+(4*9)+(3*7)+(2*9)+(1*2)=158
158 % 10 = 8
So 404597-92-8 is a valid CAS Registry Number.
