7305-18-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7305-18-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,0 and 5 respectively; the second part has 2 digits, 1 and 8 respectively.Calculate Digit Verification of CAS Registry Number 7305-18:
(6*7)+(5*3)+(4*0)+(3*5)+(2*1)+(1*8)=82
82 % 10 = 2
So 7305-18-2 is a valid CAS Registry Number.
