Check Digit Verification of cas no

The CAS Registry Mumber 203058-56-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,0,5 and 8 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 203058-56:
(8*2)+(7*0)+(6*3)+(5*0)+(4*5)+(3*8)+(2*5)+(1*6)=94
94 % 10 = 4
So 203058-56-4 is a valid CAS Registry Number.
