Check Digit Verification of cas no

The CAS Registry Mumber 203318-84-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,3,1 and 8 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 203318-84:
(8*2)+(7*0)+(6*3)+(5*3)+(4*1)+(3*8)+(2*8)+(1*4)=97
97 % 10 = 7
So 203318-84-7 is a valid CAS Registry Number.
