Check Digit Verification of cas no

The CAS Registry Mumber 55271-58-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,2,7 and 1 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 55271-58:
(7*5)+(6*5)+(5*2)+(4*7)+(3*1)+(2*5)+(1*8)=124
124 % 10 = 4
So 55271-58-4 is a valid CAS Registry Number.
