Check Digit Verification of cas no

The CAS Registry Mumber 82343-17-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,3,4 and 3 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 82343-17:
(7*8)+(6*2)+(5*3)+(4*4)+(3*3)+(2*1)+(1*7)=117
117 % 10 = 7
So 82343-17-7 is a valid CAS Registry Number.
