683-95-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 683-95-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,8 and 3 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 683-95:
(5*6)+(4*8)+(3*3)+(2*9)+(1*5)=94
94 % 10 = 4
So 683-95-4 is a valid CAS Registry Number.
