117184-13-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117184-13-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,1,8 and 4 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 117184-13:
(8*1)+(7*1)+(6*7)+(5*1)+(4*8)+(3*4)+(2*1)+(1*3)=111
111 % 10 = 1
So 117184-13-1 is a valid CAS Registry Number.
