Check Digit Verification of cas no
The CAS Registry Mumber 344-48-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,4 and 4 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 344-48:
(5*3)+(4*4)+(3*4)+(2*4)+(1*8)=59
59 % 10 = 9
So 344-48-9 is a valid CAS Registry Number.
