The CAS Registry Mumber 143741-49-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,7,4 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 143741-49:
(8*1)+(7*4)+(6*3)+(5*7)+(4*4)+(3*1)+(2*4)+(1*9)=125
125 % 10 = 5
So 143741-49-5 is a valid CAS Registry Number.
