117266-89-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117266-89-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,2,6 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 117266-89:
(8*1)+(7*1)+(6*7)+(5*2)+(4*6)+(3*6)+(2*8)+(1*9)=134
134 % 10 = 4
So 117266-89-4 is a valid CAS Registry Number.
