143023-69-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143023-69-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,0,2 and 3 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 143023-69:
(8*1)+(7*4)+(6*3)+(5*0)+(4*2)+(3*3)+(2*6)+(1*9)=92
92 % 10 = 2
So 143023-69-2 is a valid CAS Registry Number.
