1818-24-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1818-24-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,1 and 8 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1818-24:
(6*1)+(5*8)+(4*1)+(3*8)+(2*2)+(1*4)=82
82 % 10 = 2
So 1818-24-2 is a valid CAS Registry Number.
