Check Digit Verification of cas no

The CAS Registry Mumber 78423-43-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,4,2 and 3 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 78423-43:
(7*7)+(6*8)+(5*4)+(4*2)+(3*3)+(2*4)+(1*3)=145
145 % 10 = 5
So 78423-43-5 is a valid CAS Registry Number.
