Check Digit Verification of cas no

The CAS Registry Mumber 42107-73-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,1,0 and 7 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 42107-73:
(7*4)+(6*2)+(5*1)+(4*0)+(3*7)+(2*7)+(1*3)=83
83 % 10 = 3
So 42107-73-3 is a valid CAS Registry Number.
