143718-73-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 143718-73-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,7,1 and 8 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 143718-73:
(8*1)+(7*4)+(6*3)+(5*7)+(4*1)+(3*8)+(2*7)+(1*3)=134
134 % 10 = 4
So 143718-73-4 is a valid CAS Registry Number.
