Check Digit Verification of cas no

The CAS Registry Mumber 1049837-69-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,9,8,3 and 7 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1049837-69:
(9*1)+(8*0)+(7*4)+(6*9)+(5*8)+(4*3)+(3*7)+(2*6)+(1*9)=185
185 % 10 = 5
So 1049837-69-5 is a valid CAS Registry Number.
