4743-54-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4743-54-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,4 and 3 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4743-54:
(6*4)+(5*7)+(4*4)+(3*3)+(2*5)+(1*4)=98
98 % 10 = 8
So 4743-54-8 is a valid CAS Registry Number.
