684-46-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 684-46-8 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 4 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 684-46:
(5*6)+(4*8)+(3*4)+(2*4)+(1*6)=88
88 % 10 = 8
So 684-46-8 is a valid CAS Registry Number.
