Check Digit Verification of cas no

The CAS Registry Mumber 4284-75-7 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 4 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4284-75:
(6*4)+(5*2)+(4*8)+(3*4)+(2*7)+(1*5)=97
97 % 10 = 7
So 4284-75-7 is a valid CAS Registry Number.
