Check Digit Verification of cas no

The CAS Registry Mumber 203256-20-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,2,5 and 6 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 203256-20:
(8*2)+(7*0)+(6*3)+(5*2)+(4*5)+(3*6)+(2*2)+(1*0)=86
86 % 10 = 6
So 203256-20-6 is a valid CAS Registry Number.
