Check Digit Verification of cas no

The CAS Registry Mumber 840529-67-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,0,5,2 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 840529-67:
(8*8)+(7*4)+(6*0)+(5*5)+(4*2)+(3*9)+(2*6)+(1*7)=171
171 % 10 = 1
So 840529-67-1 is a valid CAS Registry Number.
