Check Digit Verification of cas no

The CAS Registry Mumber 1451091-11-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,5,1,0,9 and 1 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1451091-11:
(9*1)+(8*4)+(7*5)+(6*1)+(5*0)+(4*9)+(3*1)+(2*1)+(1*1)=124
124 % 10 = 4
So 1451091-11-4 is a valid CAS Registry Number.
