Check Digit Verification of cas no

The CAS Registry Mumber 142945-39-9 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 5 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 142945-39:
(8*1)+(7*4)+(6*2)+(5*9)+(4*4)+(3*5)+(2*3)+(1*9)=139
139 % 10 = 9
So 142945-39-9 is a valid CAS Registry Number.
