80232-99-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80232-99-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,2,3 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 80232-99:
(7*8)+(6*0)+(5*2)+(4*3)+(3*2)+(2*9)+(1*9)=111
111 % 10 = 1
So 80232-99-1 is a valid CAS Registry Number.
