Check Digit Verification of cas no

The CAS Registry Mumber 4309-16-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,0 and 9 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 4309-16:
(6*4)+(5*3)+(4*0)+(3*9)+(2*1)+(1*6)=74
74 % 10 = 4
So 4309-16-4 is a valid CAS Registry Number.
