204195-53-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 204195-53-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,1,9 and 5 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 204195-53:
(8*2)+(7*0)+(6*4)+(5*1)+(4*9)+(3*5)+(2*5)+(1*3)=109
109 % 10 = 9
So 204195-53-9 is a valid CAS Registry Number.
