Check Digit Verification of cas no

The CAS Registry Mumber 1240123-08-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,0,1,2 and 3 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1240123-08:
(9*1)+(8*2)+(7*4)+(6*0)+(5*1)+(4*2)+(3*3)+(2*0)+(1*8)=83
83 % 10 = 3
So 1240123-08-3 is a valid CAS Registry Number.
