143302-99-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143302-99-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,3,0 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 143302-99:
(8*1)+(7*4)+(6*3)+(5*3)+(4*0)+(3*2)+(2*9)+(1*9)=102
102 % 10 = 2
So 143302-99-2 is a valid CAS Registry Number.
