Check Digit Verification of cas no

The CAS Registry Mumber 103517-90-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,5,1 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 103517-90:
(8*1)+(7*0)+(6*3)+(5*5)+(4*1)+(3*7)+(2*9)+(1*0)=94
94 % 10 = 4
So 103517-90-4 is a valid CAS Registry Number.
