Check Digit Verification of cas no

The CAS Registry Mumber 4741-55-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,4 and 1 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4741-55:
(6*4)+(5*7)+(4*4)+(3*1)+(2*5)+(1*5)=93
93 % 10 = 3
So 4741-55-3 is a valid CAS Registry Number.
