Check Digit Verification of cas no

The CAS Registry Mumber 113544-23-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,5,4 and 4 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 113544-23:
(8*1)+(7*1)+(6*3)+(5*5)+(4*4)+(3*4)+(2*2)+(1*3)=93
93 % 10 = 3
So 113544-23-3 is a valid CAS Registry Number.
