6404-70-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6404-70-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,0 and 4 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6404-70:
(6*6)+(5*4)+(4*0)+(3*4)+(2*7)+(1*0)=82
82 % 10 = 2
So 6404-70-2 is a valid CAS Registry Number.
