The CAS Registry Mumber 143209-27-2 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 9 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 143209-27:
(8*1)+(7*4)+(6*3)+(5*2)+(4*0)+(3*9)+(2*2)+(1*7)=102
102 % 10 = 2
So 143209-27-2 is a valid CAS Registry Number.
