Check Digit Verification of cas no

The CAS Registry Mumber 7471-74-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,7 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 7471-74:
(6*7)+(5*4)+(4*7)+(3*1)+(2*7)+(1*4)=111
111 % 10 = 1
So 7471-74-1 is a valid CAS Registry Number.
