13301-33-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 13301-33-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,3,0 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 13301-33:
(7*1)+(6*3)+(5*3)+(4*0)+(3*1)+(2*3)+(1*3)=52
52 % 10 = 2
So 13301-33-2 is a valid CAS Registry Number.
