Check Digit Verification of cas no

The CAS Registry Mumber 1025944-49-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,5,9,4 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1025944-49:
(9*1)+(8*0)+(7*2)+(6*5)+(5*9)+(4*4)+(3*4)+(2*4)+(1*9)=143
143 % 10 = 3
So 1025944-49-3 is a valid CAS Registry Number.
