Check Digit Verification of cas no

The CAS Registry Mumber 1040424-49-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,0,4,2 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1040424-49:
(9*1)+(8*0)+(7*4)+(6*0)+(5*4)+(4*2)+(3*4)+(2*4)+(1*9)=94
94 % 10 = 4
So 1040424-49-4 is a valid CAS Registry Number.
