117113-20-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117113-20-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,1,1 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 117113-20:
(8*1)+(7*1)+(6*7)+(5*1)+(4*1)+(3*3)+(2*2)+(1*0)=79
79 % 10 = 9
So 117113-20-9 is a valid CAS Registry Number.
