Check Digit Verification of cas no

The CAS Registry Mumber 1558-08-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,5 and 8 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1558-08:
(6*1)+(5*5)+(4*5)+(3*8)+(2*0)+(1*8)=83
83 % 10 = 3
So 1558-08-3 is a valid CAS Registry Number.
