Check Digit Verification of cas no

The CAS Registry Mumber 204398-12-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,3,9 and 8 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 204398-12:
(8*2)+(7*0)+(6*4)+(5*3)+(4*9)+(3*8)+(2*1)+(1*2)=119
119 % 10 = 9
So 204398-12-9 is a valid CAS Registry Number.
