Check Digit Verification of cas no

The CAS Registry Mumber 4145-85-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,4 and 5 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4145-85:
(6*4)+(5*1)+(4*4)+(3*5)+(2*8)+(1*5)=81
81 % 10 = 1
So 4145-85-1 is a valid CAS Registry Number.
