Check Digit Verification of cas no

The CAS Registry Mumber 928049-69-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,8,0,4 and 9 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 928049-69:
(8*9)+(7*2)+(6*8)+(5*0)+(4*4)+(3*9)+(2*6)+(1*9)=198
198 % 10 = 8
So 928049-69-8 is a valid CAS Registry Number.
