Check Digit Verification of cas no

The CAS Registry Mumber 1138140-72-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,8,1,4 and 0 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1138140-72:
(9*1)+(8*1)+(7*3)+(6*8)+(5*1)+(4*4)+(3*0)+(2*7)+(1*2)=123
123 % 10 = 3
So 1138140-72-3 is a valid CAS Registry Number.
