Check Digit Verification of cas no

The CAS Registry Mumber 42300-72-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,3,0 and 0 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 42300-72:
(7*4)+(6*2)+(5*3)+(4*0)+(3*0)+(2*7)+(1*2)=71
71 % 10 = 1
So 42300-72-1 is a valid CAS Registry Number.
