The CAS Registry Mumber 23594-58-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,5,9 and 4 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 23594-58:
(7*2)+(6*3)+(5*5)+(4*9)+(3*4)+(2*5)+(1*8)=123
123 % 10 = 3
So 23594-58-3 is a valid CAS Registry Number.
