Check Digit Verification of cas no

The CAS Registry Mumber 172992-17-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,9,9 and 2 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 172992-17:
(8*1)+(7*7)+(6*2)+(5*9)+(4*9)+(3*2)+(2*1)+(1*7)=165
165 % 10 = 5
So 172992-17-5 is a valid CAS Registry Number.
