Check Digit Verification of cas no

The CAS Registry Mumber 1084-41-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,8 and 4 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1084-41:
(6*1)+(5*0)+(4*8)+(3*4)+(2*4)+(1*1)=59
59 % 10 = 9
So 1084-41-9 is a valid CAS Registry Number.
