Check Digit Verification of cas no

The CAS Registry Mumber 140136-28-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,1,3 and 6 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 140136-28:
(8*1)+(7*4)+(6*0)+(5*1)+(4*3)+(3*6)+(2*2)+(1*8)=83
83 % 10 = 3
So 140136-28-3 is a valid CAS Registry Number.
