Check Digit Verification of cas no

The CAS Registry Mumber 111439-76-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,4,3 and 9 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 111439-76:
(8*1)+(7*1)+(6*1)+(5*4)+(4*3)+(3*9)+(2*7)+(1*6)=100
100 % 10 = 0
So 111439-76-0 is a valid CAS Registry Number.
