761-17-1 Usage
General Description
Dibromoacetaldehyde diethyl acetal is a chemical compound primarily used as an intermediate in the production of pharmaceuticals and organic synthesis. It is a colorless liquid with a mild, sweet odor, and is often used as a solvent or reagent in chemical reactions. Dibromoacetaldehyde diethyl acetal is flammable and may be harmful if inhaled, ingested, or absorbed through the skin. It should be handled with care, and proper safety precautions should be taken when working with this chemical.
Check Digit Verification of cas no
The CAS Registry Mumber 761-17-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,6 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 761-17:
(5*7)+(4*6)+(3*1)+(2*1)+(1*7)=71
71 % 10 = 1
So 761-17-1 is a valid CAS Registry Number.

The bis-guanidinium toxins are a collection of natural products that display nanomolar potency against select isoforms of eukaryotic voltage-gated Na+ ion channels. We describe a synthetic strategy that enables access to four of these poisons, namely 11-saxitoxinethanoic acid, C13-acetoxy saxitoxin, decarbamoyl saxitoxin, and saxitoxin. Highlights of this work include an unusual Mislow–Evans rearrangement and a late-stage Stille ketene acetal coupling. The IC50 value of 11-saxitoxinethanoic acid was measured against rat NaV1.4, and found to be 17.0 nm, similar to those of the sulfated toxins gonyautoxin II and III.
