66854-58-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 66854-58-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,8,5 and 4 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 66854-58:
(7*6)+(6*6)+(5*8)+(4*5)+(3*4)+(2*5)+(1*8)=168
168 % 10 = 8
So 66854-58-8 is a valid CAS Registry Number.
