Check Digit Verification of cas no
The CAS Registry Mumber 117-45-3 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 5 respectively.Calculate Digit Verification of CAS Registry Number 117-45:
(5*1)+(4*1)+(3*7)+(2*4)+(1*5)=43
43 % 10 = 3
So 117-45-3 is a valid CAS Registry Number.
