Check Digit Verification of cas no

The CAS Registry Mumber 1898-05-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,9 and 8 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1898-05:
(6*1)+(5*8)+(4*9)+(3*8)+(2*0)+(1*5)=111
111 % 10 = 1
So 1898-05-1 is a valid CAS Registry Number.
