The CAS Registry Mumber 143208-38-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,2,0 and 8 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 143208-38:
(8*1)+(7*4)+(6*3)+(5*2)+(4*0)+(3*8)+(2*3)+(1*8)=102
102 % 10 = 2
So 143208-38-2 is a valid CAS Registry Number.
