13022-03-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 13022-03-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,0,2 and 2 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 13022-03:
(7*1)+(6*3)+(5*0)+(4*2)+(3*2)+(2*0)+(1*3)=42
42 % 10 = 2
So 13022-03-2 is a valid CAS Registry Number.
