7623-03-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7623-03-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,2 and 3 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 7623-03:
(6*7)+(5*6)+(4*2)+(3*3)+(2*0)+(1*3)=92
92 % 10 = 2
So 7623-03-2 is a valid CAS Registry Number.
