206561-66-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 206561-66-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,6,5,6 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 206561-66:
(8*2)+(7*0)+(6*6)+(5*5)+(4*6)+(3*1)+(2*6)+(1*6)=122
122 % 10 = 2
So 206561-66-2 is a valid CAS Registry Number.
