7234-40-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7234-40-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,3 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 7234-40:
(6*7)+(5*2)+(4*3)+(3*4)+(2*4)+(1*0)=84
84 % 10 = 4
So 7234-40-4 is a valid CAS Registry Number.
