165-42-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 165-42-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,6 and 5 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 165-42:
(5*1)+(4*6)+(3*5)+(2*4)+(1*2)=54
54 % 10 = 4
So 165-42-4 is a valid CAS Registry Number.
