The CAS Registry Mumber 802333-81-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,0,2,3,3 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 802333-81:
(8*8)+(7*0)+(6*2)+(5*3)+(4*3)+(3*3)+(2*8)+(1*1)=129
129 % 10 = 9
So 802333-81-9 is a valid CAS Registry Number.
