Check Digit Verification of cas no

The CAS Registry Mumber 4163-83-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,6 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4163-83:
(6*4)+(5*1)+(4*6)+(3*3)+(2*8)+(1*3)=81
81 % 10 = 1
So 4163-83-1 is a valid CAS Registry Number.
