143391-47-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143391-47-3 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 7 respectively.
Calculate Digit Verification of CAS Registry Number 143391-47:
(8*1)+(7*4)+(6*3)+(5*3)+(4*9)+(3*1)+(2*4)+(1*7)=123
123 % 10 = 3
So 143391-47-3 is a valid CAS Registry Number.
