Check Digit Verification of cas no

The CAS Registry Mumber 444313-01-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,4,3,1 and 3 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 444313-01:
(8*4)+(7*4)+(6*4)+(5*3)+(4*1)+(3*3)+(2*0)+(1*1)=113
113 % 10 = 3
So 444313-01-3 is a valid CAS Registry Number.
