204381-53-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 204381-53-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,3,8 and 1 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 204381-53:
(8*2)+(7*0)+(6*4)+(5*3)+(4*8)+(3*1)+(2*5)+(1*3)=103
103 % 10 = 3
So 204381-53-3 is a valid CAS Registry Number.
