161117-11-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 161117-11-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,1,1 and 7 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 161117-11:
(8*1)+(7*6)+(6*1)+(5*1)+(4*1)+(3*7)+(2*1)+(1*1)=89
89 % 10 = 9
So 161117-11-9 is a valid CAS Registry Number.
