80334-50-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80334-50-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,3,3 and 4 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 80334-50:
(7*8)+(6*0)+(5*3)+(4*3)+(3*4)+(2*5)+(1*0)=105
105 % 10 = 5
So 80334-50-5 is a valid CAS Registry Number.
