Check Digit Verification of cas no

The CAS Registry Mumber 920339-02-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,0,3,3 and 9 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 920339-02:
(8*9)+(7*2)+(6*0)+(5*3)+(4*3)+(3*9)+(2*0)+(1*2)=142
142 % 10 = 2
So 920339-02-2 is a valid CAS Registry Number.
