Check Digit Verification of cas no

The CAS Registry Mumber 173282-19-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,2,8 and 2 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 173282-19:
(8*1)+(7*7)+(6*3)+(5*2)+(4*8)+(3*2)+(2*1)+(1*9)=134
134 % 10 = 4
So 173282-19-4 is a valid CAS Registry Number.
