Check Digit Verification of cas no

The CAS Registry Mumber 557111-38-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,5,7,1,1 and 1 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 557111-38:
(8*5)+(7*5)+(6*7)+(5*1)+(4*1)+(3*1)+(2*3)+(1*8)=143
143 % 10 = 3
So 557111-38-3 is a valid CAS Registry Number.
