Check Digit Verification of cas no
The CAS Registry Mumber 18465-39-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,4,6 and 5 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 18465-39:
(7*1)+(6*8)+(5*4)+(4*6)+(3*5)+(2*3)+(1*9)=129
129 % 10 = 9
So 18465-39-9 is a valid CAS Registry Number.
