474093-54-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 474093-54-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,4,0,9 and 3 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 474093-54:
(8*4)+(7*7)+(6*4)+(5*0)+(4*9)+(3*3)+(2*5)+(1*4)=164
164 % 10 = 4
So 474093-54-4 is a valid CAS Registry Number.
