6665-68-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6665-68-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,6 and 5 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 6665-68:
(6*6)+(5*6)+(4*6)+(3*5)+(2*6)+(1*8)=125
125 % 10 = 5
So 6665-68-5 is a valid CAS Registry Number.
