Check Digit Verification of cas no

The CAS Registry Mumber 4288-20-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,8 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4288-20:
(6*4)+(5*2)+(4*8)+(3*8)+(2*2)+(1*0)=94
94 % 10 = 4
So 4288-20-4 is a valid CAS Registry Number.
