The CAS Registry Mumber 725712-74-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,2,5,7,1 and 2 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 725712-74:
(8*7)+(7*2)+(6*5)+(5*7)+(4*1)+(3*2)+(2*7)+(1*4)=163
163 % 10 = 3
So 725712-74-3 is a valid CAS Registry Number.
