80109-48-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80109-48-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,1,0 and 9 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 80109-48:
(7*8)+(6*0)+(5*1)+(4*0)+(3*9)+(2*4)+(1*8)=104
104 % 10 = 4
So 80109-48-4 is a valid CAS Registry Number.
