1333-38-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1333-38-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,3 and 3 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1333-38:
(6*1)+(5*3)+(4*3)+(3*3)+(2*3)+(1*8)=56
56 % 10 = 6
So 1333-38-6 is a valid CAS Registry Number.
