Check Digit Verification of cas no

The CAS Registry Mumber 156176-90-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,1,7 and 6 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 156176-90:
(8*1)+(7*5)+(6*6)+(5*1)+(4*7)+(3*6)+(2*9)+(1*0)=148
148 % 10 = 8
So 156176-90-8 is a valid CAS Registry Number.
