80233-05-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80233-05-2 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 3 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 80233-05:
(7*8)+(6*0)+(5*2)+(4*3)+(3*3)+(2*0)+(1*5)=92
92 % 10 = 2
So 80233-05-2 is a valid CAS Registry Number.
