129121-68-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129121-68-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,1,2 and 1 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 129121-68:
(8*1)+(7*2)+(6*9)+(5*1)+(4*2)+(3*1)+(2*6)+(1*8)=112
112 % 10 = 2
So 129121-68-2 is a valid CAS Registry Number.

Clavamine, a new insecticidal toxin isolated from the venom of Joro spider (Nephila clavata) was totally synthesized in order to confirm the proposed structure. In clavamine, a fragment of glycylalanine is inserted in the structure of NSTX-3, a New Guinean spider toxin. The synthesis determined the chemical structure of clavamine unambiguously.
