1204209-03-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1204209-03-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,4,2,0 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1204209-03:
(9*1)+(8*2)+(7*0)+(6*4)+(5*2)+(4*0)+(3*9)+(2*0)+(1*3)=89
89 % 10 = 9
So 1204209-03-9 is a valid CAS Registry Number.
