Check Digit Verification of cas no

The CAS Registry Mumber 1843-91-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,4 and 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1843-91:
(6*1)+(5*8)+(4*4)+(3*3)+(2*9)+(1*1)=90
90 % 10 = 0
So 1843-91-0 is a valid CAS Registry Number.
