204441-84-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 204441-84-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,4,4 and 1 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 204441-84:
(8*2)+(7*0)+(6*4)+(5*4)+(4*4)+(3*1)+(2*8)+(1*4)=99
99 % 10 = 9
So 204441-84-9 is a valid CAS Registry Number.
