3321-13-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 3321-13-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,2 and 1 respectively; the second part has 2 digits, 1 and 3 respectively.Calculate Digit Verification of CAS Registry Number 3321-13:
(6*3)+(5*3)+(4*2)+(3*1)+(2*1)+(1*3)=49
49 % 10 = 9
So 3321-13-9 is a valid CAS Registry Number.
