4743-40-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4743-40-2 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, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4743-40:
(6*4)+(5*7)+(4*4)+(3*3)+(2*4)+(1*0)=92
92 % 10 = 2
So 4743-40-2 is a valid CAS Registry Number.
