Check Digit Verification of cas no

The CAS Registry Mumber 4328-05-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,2 and 8 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4328-05:
(6*4)+(5*3)+(4*2)+(3*8)+(2*0)+(1*5)=76
76 % 10 = 6
So 4328-05-6 is a valid CAS Registry Number.
