143457-07-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143457-07-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,4,5 and 7 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 143457-07:
(8*1)+(7*4)+(6*3)+(5*4)+(4*5)+(3*7)+(2*0)+(1*7)=122
122 % 10 = 2
So 143457-07-2 is a valid CAS Registry Number.
