The CAS Registry Mumber 731859-28-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,3,1,8,5 and 9 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 731859-28:
(8*7)+(7*3)+(6*1)+(5*8)+(4*5)+(3*9)+(2*2)+(1*8)=182
182 % 10 = 2
So 731859-28-2 is a valid CAS Registry Number.
