Check Digit Verification of cas no

The CAS Registry Mumber 171668-15-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,6,6 and 8 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 171668-15:
(8*1)+(7*7)+(6*1)+(5*6)+(4*6)+(3*8)+(2*1)+(1*5)=148
148 % 10 = 8
So 171668-15-8 is a valid CAS Registry Number.
