Check Digit Verification of cas no
The CAS Registry Mumber 663-41-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,6 and 3 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 663-41:
(5*6)+(4*6)+(3*3)+(2*4)+(1*1)=72
72 % 10 = 2
So 663-41-2 is a valid CAS Registry Number.
