Check Digit Verification of cas no

The CAS Registry Mumber 105-61-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,0 and 5 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 105-61:
(5*1)+(4*0)+(3*5)+(2*6)+(1*1)=33
33 % 10 = 3
So 105-61-3 is a valid CAS Registry Number.
