Check Digit Verification of cas no

The CAS Registry Mumber 178804-90-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,8,8,0 and 4 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 178804-90:
(8*1)+(7*7)+(6*8)+(5*8)+(4*0)+(3*4)+(2*9)+(1*0)=175
175 % 10 = 5
So 178804-90-5 is a valid CAS Registry Number.
