211-11-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 211-11-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,1 and 1 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 211-11:
(5*2)+(4*1)+(3*1)+(2*1)+(1*1)=20
20 % 10 = 0
So 211-11-0 is a valid CAS Registry Number.
