Check Digit Verification of cas no

The CAS Registry Mumber 40842-03-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,8,4 and 2 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 40842-03:
(7*4)+(6*0)+(5*8)+(4*4)+(3*2)+(2*0)+(1*3)=93
93 % 10 = 3
So 40842-03-3 is a valid CAS Registry Number.
