143023-66-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143023-66-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,0,2 and 3 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 143023-66:
(8*1)+(7*4)+(6*3)+(5*0)+(4*2)+(3*3)+(2*6)+(1*6)=89
89 % 10 = 9
So 143023-66-9 is a valid CAS Registry Number.
