Check Digit Verification of cas no

The CAS Registry Mumber 4339-77-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,3 and 9 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4339-77:
(6*4)+(5*3)+(4*3)+(3*9)+(2*7)+(1*7)=99
99 % 10 = 9
So 4339-77-9 is a valid CAS Registry Number.
