The CAS Registry Mumber 105539-53-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,5,3 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 105539-53:
(8*1)+(7*0)+(6*5)+(5*5)+(4*3)+(3*9)+(2*5)+(1*3)=115
115 % 10 = 5
So 105539-53-5 is a valid CAS Registry Number.
