Check Digit Verification of cas no

The CAS Registry Mumber 3450-61-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,5 and 0 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3450-61:
(6*3)+(5*4)+(4*5)+(3*0)+(2*6)+(1*1)=71
71 % 10 = 1
So 3450-61-1 is a valid CAS Registry Number.
