4703-33-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4703-33-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,0 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4703-33:
(6*4)+(5*7)+(4*0)+(3*3)+(2*3)+(1*3)=77
77 % 10 = 7
So 4703-33-7 is a valid CAS Registry Number.
