143033-91-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143033-91-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,0,3 and 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 143033-91:
(8*1)+(7*4)+(6*3)+(5*0)+(4*3)+(3*3)+(2*9)+(1*1)=94
94 % 10 = 4
So 143033-91-4 is a valid CAS Registry Number.
