320-18-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 320-18-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,2 and 0 respectively; the second part has 2 digits, 1 and 8 respectively.Calculate Digit Verification of CAS Registry Number 320-18:
(5*3)+(4*2)+(3*0)+(2*1)+(1*8)=33
33 % 10 = 3
So 320-18-3 is a valid CAS Registry Number.
