Check Digit Verification of cas no

The CAS Registry Mumber 140401-45-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,4,0 and 1 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 140401-45:
(8*1)+(7*4)+(6*0)+(5*4)+(4*0)+(3*1)+(2*4)+(1*5)=72
72 % 10 = 2
So 140401-45-2 is a valid CAS Registry Number.
