Check Digit Verification of cas no
The CAS Registry Mumber 423-41-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,2 and 3 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 423-41:
(5*4)+(4*2)+(3*3)+(2*4)+(1*1)=46
46 % 10 = 6
So 423-41-6 is a valid CAS Registry Number.
