Check Digit Verification of cas no

The CAS Registry Mumber 4832-48-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,3 and 2 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4832-48:
(6*4)+(5*8)+(4*3)+(3*2)+(2*4)+(1*8)=98
98 % 10 = 8
So 4832-48-8 is a valid CAS Registry Number.
