The CAS Registry Mumber 727740-59-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,2,7,7,4 and 0 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 727740-59:
(8*7)+(7*2)+(6*7)+(5*7)+(4*4)+(3*0)+(2*5)+(1*9)=182
182 % 10 = 2
So 727740-59-2 is a valid CAS Registry Number.
