Check Digit Verification of cas no

The CAS Registry Mumber 203440-78-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,4,4 and 0 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 203440-78:
(8*2)+(7*0)+(6*3)+(5*4)+(4*4)+(3*0)+(2*7)+(1*8)=92
92 % 10 = 2
So 203440-78-2 is a valid CAS Registry Number.
