Check Digit Verification of cas no

The CAS Registry Mumber 140209-67-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,2,0 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 140209-67:
(8*1)+(7*4)+(6*0)+(5*2)+(4*0)+(3*9)+(2*6)+(1*7)=92
92 % 10 = 2
So 140209-67-2 is a valid CAS Registry Number.
