80433-78-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80433-78-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,4,3 and 3 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 80433-78:
(7*8)+(6*0)+(5*4)+(4*3)+(3*3)+(2*7)+(1*8)=119
119 % 10 = 9
So 80433-78-9 is a valid CAS Registry Number.
