Check Digit Verification of cas no

The CAS Registry Mumber 81975-17-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,9,7 and 5 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 81975-17:
(7*8)+(6*1)+(5*9)+(4*7)+(3*5)+(2*1)+(1*7)=159
159 % 10 = 9
So 81975-17-9 is a valid CAS Registry Number.
