Check Digit Verification of cas no

The CAS Registry Mumber 145948-66-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,9,4 and 8 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 145948-66:
(8*1)+(7*4)+(6*5)+(5*9)+(4*4)+(3*8)+(2*6)+(1*6)=169
169 % 10 = 9
So 145948-66-9 is a valid CAS Registry Number.
