Check Digit Verification of cas no

The CAS Registry Mumber 112543-78-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,5,4 and 3 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 112543-78:
(8*1)+(7*1)+(6*2)+(5*5)+(4*4)+(3*3)+(2*7)+(1*8)=99
99 % 10 = 9
So 112543-78-9 is a valid CAS Registry Number.
