Check Digit Verification of cas no

The CAS Registry Mumber 1489-91-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,8 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1489-91:
(6*1)+(5*4)+(4*8)+(3*9)+(2*9)+(1*1)=104
104 % 10 = 4
So 1489-91-4 is a valid CAS Registry Number.
