206121-85-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 206121-85-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,6,1,2 and 1 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 206121-85:
(8*2)+(7*0)+(6*6)+(5*1)+(4*2)+(3*1)+(2*8)+(1*5)=89
89 % 10 = 9
So 206121-85-9 is a valid CAS Registry Number.
