Check Digit Verification of cas no

The CAS Registry Mumber 158574-90-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,5,7 and 4 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 158574-90:
(8*1)+(7*5)+(6*8)+(5*5)+(4*7)+(3*4)+(2*9)+(1*0)=174
174 % 10 = 4
So 158574-90-4 is a valid CAS Registry Number.
