Check Digit Verification of cas no

The CAS Registry Mumber 188409-89-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,4,0 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 188409-89:
(8*1)+(7*8)+(6*8)+(5*4)+(4*0)+(3*9)+(2*8)+(1*9)=184
184 % 10 = 4
So 188409-89-4 is a valid CAS Registry Number.
