Check Digit Verification of cas no

The CAS Registry Mumber 142944-53-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,9,4 and 4 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 142944-53:
(8*1)+(7*4)+(6*2)+(5*9)+(4*4)+(3*4)+(2*5)+(1*3)=134
134 % 10 = 4
So 142944-53-4 is a valid CAS Registry Number.
