The CAS Registry Mumber 190143-66-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,1,4 and 3 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 190143-66:
(8*1)+(7*9)+(6*0)+(5*1)+(4*4)+(3*3)+(2*6)+(1*6)=119
119 % 10 = 9
