Check Digit Verification of cas no

The CAS Registry Mumber 140933-93-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,9,3 and 3 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 140933-93:
(8*1)+(7*4)+(6*0)+(5*9)+(4*3)+(3*3)+(2*9)+(1*3)=123
123 % 10 = 3
So 140933-93-3 is a valid CAS Registry Number.
