Check Digit Verification of cas no

The CAS Registry Mumber 172917-97-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,9,1 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 172917-97:
(8*1)+(7*7)+(6*2)+(5*9)+(4*1)+(3*7)+(2*9)+(1*7)=164
164 % 10 = 4
So 172917-97-4 is a valid CAS Registry Number.
