Check Digit Verification of cas no
The CAS Registry Mumber 40331-38-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,3,3 and 1 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 40331-38:
(7*4)+(6*0)+(5*3)+(4*3)+(3*1)+(2*3)+(1*8)=72
72 % 10 = 2
So 40331-38-2 is a valid CAS Registry Number.
