345-65-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 345-65-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,4 and 5 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 345-65:
(5*3)+(4*4)+(3*5)+(2*6)+(1*5)=63
63 % 10 = 3
So 345-65-3 is a valid CAS Registry Number.
