Check Digit Verification of cas no

The CAS Registry Mumber 202802-90-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,2,8,0 and 2 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 202802-90:
(8*2)+(7*0)+(6*2)+(5*8)+(4*0)+(3*2)+(2*9)+(1*0)=92
92 % 10 = 2
So 202802-90-2 is a valid CAS Registry Number.
