343262-89-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 343262-89-5 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 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 343262-89:
(8*3)+(7*4)+(6*3)+(5*2)+(4*6)+(3*2)+(2*8)+(1*9)=135
135 % 10 = 5
So 343262-89-5 is a valid CAS Registry Number.
