Check Digit Verification of cas no

The CAS Registry Mumber 5558-16-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,5 and 8 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 5558-16:
(6*5)+(5*5)+(4*5)+(3*8)+(2*1)+(1*6)=107
107 % 10 = 7
So 5558-16-7 is a valid CAS Registry Number.
