Check Digit Verification of cas no
The CAS Registry Mumber 14027-75-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,0,2 and 7 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 14027-75:
(7*1)+(6*4)+(5*0)+(4*2)+(3*7)+(2*7)+(1*5)=79
79 % 10 = 9
So 14027-75-9 is a valid CAS Registry Number.
