Check Digit Verification of cas no

The CAS Registry Mumber 282735-73-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,2,7,3 and 5 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 282735-73:
(8*2)+(7*8)+(6*2)+(5*7)+(4*3)+(3*5)+(2*7)+(1*3)=163
163 % 10 = 3
So 282735-73-3 is a valid CAS Registry Number.
