143391-43-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143391-43-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,3,9 and 1 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 143391-43:
(8*1)+(7*4)+(6*3)+(5*3)+(4*9)+(3*1)+(2*4)+(1*3)=119
119 % 10 = 9
So 143391-43-9 is a valid CAS Registry Number.
