566-96-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 566-96-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,6 and 6 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 566-96:
(5*5)+(4*6)+(3*6)+(2*9)+(1*6)=91
91 % 10 = 1
So 566-96-1 is a valid CAS Registry Number.
