Check Digit Verification of cas no

The CAS Registry Mumber 403819-49-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,3,8,1 and 9 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 403819-49:
(8*4)+(7*0)+(6*3)+(5*8)+(4*1)+(3*9)+(2*4)+(1*9)=138
138 % 10 = 8
So 403819-49-8 is a valid CAS Registry Number.
