Check Digit Verification of cas no

The CAS Registry Mumber 140362-03-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,3,6 and 2 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 140362-03:
(8*1)+(7*4)+(6*0)+(5*3)+(4*6)+(3*2)+(2*0)+(1*3)=84
84 % 10 = 4
So 140362-03-4 is a valid CAS Registry Number.
