117309-97-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117309-97-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,3,0 and 9 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 117309-97:
(8*1)+(7*1)+(6*7)+(5*3)+(4*0)+(3*9)+(2*9)+(1*7)=124
124 % 10 = 4
So 117309-97-4 is a valid CAS Registry Number.
