Check Digit Verification of cas no

The CAS Registry Mumber 889409-32-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,9,4,0 and 9 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 889409-32:
(8*8)+(7*8)+(6*9)+(5*4)+(4*0)+(3*9)+(2*3)+(1*2)=229
229 % 10 = 9
So 889409-32-9 is a valid CAS Registry Number.
