80393-03-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80393-03-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,3,9 and 3 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 80393-03:
(7*8)+(6*0)+(5*3)+(4*9)+(3*3)+(2*0)+(1*3)=119
119 % 10 = 9
So 80393-03-9 is a valid CAS Registry Number.
