206256-43-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 206256-43-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,6,2,5 and 6 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 206256-43:
(8*2)+(7*0)+(6*6)+(5*2)+(4*5)+(3*6)+(2*4)+(1*3)=111
111 % 10 = 1
So 206256-43-1 is a valid CAS Registry Number.
