3321-45-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 3321-45-7 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, 4 and 5 respectively.Calculate Digit Verification of CAS Registry Number 3321-45:
(6*3)+(5*3)+(4*2)+(3*1)+(2*4)+(1*5)=57
57 % 10 = 7
So 3321-45-7 is a valid CAS Registry Number.
