The CAS Registry Mumber 25884-43-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,8,8 and 4 respectively; the second part has 2 digits, 4 and 3 respectively.Calculate Digit Verification of CAS Registry Number 25884-43:
(7*2)+(6*5)+(5*8)+(4*8)+(3*4)+(2*4)+(1*3)=139
139 % 10 = 9
So 25884-43-9 is a valid CAS Registry Number.
