206-20-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 206-20-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,0 and 6 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 206-20:
(5*2)+(4*0)+(3*6)+(2*2)+(1*0)=32
32 % 10 = 2
So 206-20-2 is a valid CAS Registry Number.
