Check Digit Verification of cas no

The CAS Registry Mumber 4394-99-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,9 and 4 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4394-99:
(6*4)+(5*3)+(4*9)+(3*4)+(2*9)+(1*9)=114
114 % 10 = 4
So 4394-99-4 is a valid CAS Registry Number.
