204912-99-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 204912-99-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,9,1 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 204912-99:
(8*2)+(7*0)+(6*4)+(5*9)+(4*1)+(3*2)+(2*9)+(1*9)=122
122 % 10 = 2
So 204912-99-2 is a valid CAS Registry Number.
