128433-84-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128433-84-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,4,3 and 3 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 128433-84:
(8*1)+(7*2)+(6*8)+(5*4)+(4*3)+(3*3)+(2*8)+(1*4)=131
131 % 10 = 1
So 128433-84-1 is a valid CAS Registry Number.
