Check Digit Verification of cas no
The CAS Registry Mumber 13943-58-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,9,4 and 3 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 13943-58:
(7*1)+(6*3)+(5*9)+(4*4)+(3*3)+(2*5)+(1*8)=113
113 % 10 = 3
So 13943-58-3 is a valid CAS Registry Number.
