Check Digit Verification of cas no

The CAS Registry Mumber 4105-55-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,0 and 5 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4105-55:
(6*4)+(5*1)+(4*0)+(3*5)+(2*5)+(1*5)=59
59 % 10 = 9
So 4105-55-9 is a valid CAS Registry Number.
