Check Digit Verification of cas no

The CAS Registry Mumber 443889-52-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,3,8,8 and 9 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 443889-52:
(8*4)+(7*4)+(6*3)+(5*8)+(4*8)+(3*9)+(2*5)+(1*2)=189
189 % 10 = 9
So 443889-52-9 is a valid CAS Registry Number.
