Check Digit Verification of cas no

The CAS Registry Mumber 4431-30-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,3 and 1 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4431-30:
(6*4)+(5*4)+(4*3)+(3*1)+(2*3)+(1*0)=65
65 % 10 = 5
So 4431-30-5 is a valid CAS Registry Number.
