Check Digit Verification of cas no

The CAS Registry Mumber 2199-88-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,9 and 9 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2199-88:
(6*2)+(5*1)+(4*9)+(3*9)+(2*8)+(1*8)=104
104 % 10 = 4
So 2199-88-4 is a valid CAS Registry Number.
