2220-48-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2220-48-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,2 and 0 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2220-48:
(6*2)+(5*2)+(4*2)+(3*0)+(2*4)+(1*8)=46
46 % 10 = 6
So 2220-48-6 is a valid CAS Registry Number.
