Check Digit Verification of cas no

The CAS Registry Mumber 140863-12-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,8,6 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 140863-12:
(8*1)+(7*4)+(6*0)+(5*8)+(4*6)+(3*3)+(2*1)+(1*2)=113
113 % 10 = 3
So 140863-12-3 is a valid CAS Registry Number.
