Check Digit Verification of cas no

The CAS Registry Mumber 4441-94-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,4 and 1 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4441-94:
(6*4)+(5*4)+(4*4)+(3*1)+(2*9)+(1*4)=85
85 % 10 = 5
So 4441-94-5 is a valid CAS Registry Number.
