343266-73-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 343266-73-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,3,2,6 and 6 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 343266-73:
(8*3)+(7*4)+(6*3)+(5*2)+(4*6)+(3*6)+(2*7)+(1*3)=139
139 % 10 = 9
So 343266-73-9 is a valid CAS Registry Number.
