Check Digit Verification of cas no

The CAS Registry Mumber 115944-89-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,5,9,4 and 4 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 115944-89:
(8*1)+(7*1)+(6*5)+(5*9)+(4*4)+(3*4)+(2*8)+(1*9)=143
143 % 10 = 3
So 115944-89-3 is a valid CAS Registry Number.
