4355-41-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4355-41-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,5 and 5 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4355-41:
(6*4)+(5*3)+(4*5)+(3*5)+(2*4)+(1*1)=83
83 % 10 = 3
So 4355-41-3 is a valid CAS Registry Number.
