Check Digit Verification of cas no
The CAS Registry Mumber 117-44-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,1 and 7 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 117-44:
(5*1)+(4*1)+(3*7)+(2*4)+(1*4)=42
42 % 10 = 2
So 117-44-2 is a valid CAS Registry Number.
