6818-41-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 6818-41-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,8,1 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.Calculate Digit Verification of CAS Registry Number 6818-41:
(6*6)+(5*8)+(4*1)+(3*8)+(2*4)+(1*1)=113
113 % 10 = 3
So 6818-41-3 is a valid CAS Registry Number.
