59146-43-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 59146-43-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,1,4 and 6 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 59146-43:
(7*5)+(6*9)+(5*1)+(4*4)+(3*6)+(2*4)+(1*3)=139
139 % 10 = 9
So 59146-43-9 is a valid CAS Registry Number.
