7403-35-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7403-35-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,0 and 3 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 7403-35:
(6*7)+(5*4)+(4*0)+(3*3)+(2*3)+(1*5)=82
82 % 10 = 2
So 7403-35-2 is a valid CAS Registry Number.
