Check Digit Verification of cas no

The CAS Registry Mumber 99432-98-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,4,3 and 2 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 99432-98:
(7*9)+(6*9)+(5*4)+(4*3)+(3*2)+(2*9)+(1*8)=181
181 % 10 = 1
So 99432-98-1 is a valid CAS Registry Number.
