205433-47-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 205433-47-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,4,3 and 3 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 205433-47:
(8*2)+(7*0)+(6*5)+(5*4)+(4*3)+(3*3)+(2*4)+(1*7)=102
102 % 10 = 2
So 205433-47-2 is a valid CAS Registry Number.
