Check Digit Verification of cas no

The CAS Registry Mumber 143427-14-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,4,2 and 7 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 143427-14:
(8*1)+(7*4)+(6*3)+(5*4)+(4*2)+(3*7)+(2*1)+(1*4)=109
109 % 10 = 9
So 143427-14-9 is a valid CAS Registry Number.
