Check Digit Verification of cas no

The CAS Registry Mumber 160503-83-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,0,5,0 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 160503-83:
(8*1)+(7*6)+(6*0)+(5*5)+(4*0)+(3*3)+(2*8)+(1*3)=103
103 % 10 = 3
So 160503-83-3 is a valid CAS Registry Number.
