219794-81-7 Usage
General Description
The chemical compound (2R,4S,5R)-2-Hydroxymethyl-5-ethylquinuclidine, also known as HEQ, is a quinuclidine derivative with a hydroxymethyl and ethyl group attached to the quinuclidine ring. It belongs to the class of organic compounds known as quinuclidines, which are bicyclic compounds containing a piperidine ring fused to a quinuclidine ring. HEQ is a chiral molecule, with the stereochemistry specified in the name, and it is commonly used as a building block in the synthesis of pharmaceuticals and other organic compounds. Its hydroxymethyl group makes HEQ a valuable intermediate in the production of various drugs and active pharmaceutical ingredients.
Check Digit Verification of cas no
The CAS Registry Mumber 219794-81-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,7,9 and 4 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 219794-81:
(8*2)+(7*1)+(6*9)+(5*7)+(4*9)+(3*4)+(2*8)+(1*1)=177
177 % 10 = 7
So 219794-81-7 is a valid CAS Registry Number.
