Check Digit Verification of cas no

The CAS Registry Mumber 40203-70-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,2,0 and 3 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 40203-70:
(7*4)+(6*0)+(5*2)+(4*0)+(3*3)+(2*7)+(1*0)=61
61 % 10 = 1
So 40203-70-1 is a valid CAS Registry Number.
