7220-42-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7220-42-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,2 and 0 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 7220-42:
(6*7)+(5*2)+(4*2)+(3*0)+(2*4)+(1*2)=70
70 % 10 = 0
So 7220-42-0 is a valid CAS Registry Number.
