The CAS Registry Mumber 243849-46-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,3,8,4 and 9 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 243849-46:
(8*2)+(7*4)+(6*3)+(5*8)+(4*4)+(3*9)+(2*4)+(1*6)=159
159 % 10 = 9
So 243849-46-9 is a valid CAS Registry Number.
