Check Digit Verification of cas no
The CAS Registry Mumber 6404-46-2 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, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 6404-46:
(6*6)+(5*4)+(4*0)+(3*4)+(2*4)+(1*6)=82
82 % 10 = 2
So 6404-46-2 is a valid CAS Registry Number.
