Check Digit Verification of cas no

The CAS Registry Mumber 4340-42-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,4 and 0 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 4340-42:
(6*4)+(5*3)+(4*4)+(3*0)+(2*4)+(1*2)=65
65 % 10 = 5
So 4340-42-5 is a valid CAS Registry Number.
