Check Digit Verification of cas no

The CAS Registry Mumber 840502-17-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,0,5,0 and 2 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 840502-17:
(8*8)+(7*4)+(6*0)+(5*5)+(4*0)+(3*2)+(2*1)+(1*7)=132
132 % 10 = 2
So 840502-17-2 is a valid CAS Registry Number.
