Check Digit Verification of cas no

The CAS Registry Mumber 143919-67-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,9,1 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 143919-67:
(8*1)+(7*4)+(6*3)+(5*9)+(4*1)+(3*9)+(2*6)+(1*7)=149
149 % 10 = 9
So 143919-67-9 is a valid CAS Registry Number.
