Check Digit Verification of cas no

The CAS Registry Mumber 174904-93-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,9,0 and 4 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 174904-93:
(8*1)+(7*7)+(6*4)+(5*9)+(4*0)+(3*4)+(2*9)+(1*3)=159
159 % 10 = 9
So 174904-93-9 is a valid CAS Registry Number.
