Check Digit Verification of cas no
The CAS Registry Mumber 6451-11-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,5 and 1 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6451-11:
(6*6)+(5*4)+(4*5)+(3*1)+(2*1)+(1*1)=82
82 % 10 = 2
So 6451-11-2 is a valid CAS Registry Number.
