23589-43-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 23589-43-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,5,8 and 9 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 23589-43:
(7*2)+(6*3)+(5*5)+(4*8)+(3*9)+(2*4)+(1*3)=127
127 % 10 = 7
So 23589-43-7 is a valid CAS Registry Number.
