117719-22-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117719-22-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,7,1 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 117719-22:
(8*1)+(7*1)+(6*7)+(5*7)+(4*1)+(3*9)+(2*2)+(1*2)=129
129 % 10 = 9
So 117719-22-9 is a valid CAS Registry Number.
