Check Digit Verification of cas no

The CAS Registry Mumber 140939-60-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,9,3 and 9 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 140939-60:
(8*1)+(7*4)+(6*0)+(5*9)+(4*3)+(3*9)+(2*6)+(1*0)=132
132 % 10 = 2
So 140939-60-2 is a valid CAS Registry Number.
