Check Digit Verification of cas no

The CAS Registry Mumber 40321-00-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,3,2 and 1 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 40321-00:
(7*4)+(6*0)+(5*3)+(4*2)+(3*1)+(2*0)+(1*0)=54
54 % 10 = 4
So 40321-00-4 is a valid CAS Registry Number.
