Check Digit Verification of cas no

The CAS Registry Mumber 142452-63-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,4,5 and 2 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 142452-63:
(8*1)+(7*4)+(6*2)+(5*4)+(4*5)+(3*2)+(2*6)+(1*3)=109
109 % 10 = 9
So 142452-63-9 is a valid CAS Registry Number.
