4444-34-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4444-34-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,4 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4444-34:
(6*4)+(5*4)+(4*4)+(3*4)+(2*3)+(1*4)=82
82 % 10 = 2
So 4444-34-2 is a valid CAS Registry Number.
