4672-45-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4672-45-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,7 and 2 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4672-45:
(6*4)+(5*6)+(4*7)+(3*2)+(2*4)+(1*5)=101
101 % 10 = 1
So 4672-45-1 is a valid CAS Registry Number.
