Check Digit Verification of cas no

The CAS Registry Mumber 4042-80-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,4 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4042-80:
(6*4)+(5*0)+(4*4)+(3*2)+(2*8)+(1*0)=62
62 % 10 = 2
So 4042-80-2 is a valid CAS Registry Number.
