Check Digit Verification of cas no

The CAS Registry Mumber 726203-81-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,2,6,2,0 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 726203-81:
(8*7)+(7*2)+(6*6)+(5*2)+(4*0)+(3*3)+(2*8)+(1*1)=142
142 % 10 = 2
So 726203-81-2 is a valid CAS Registry Number.
